what's the solution of the equation 4[x+2(3x-7)]=22x-65
Answer:
x = -3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x+2(3x−7))=22x−65
Step 1: Simplify both sides of the equation.
4(x+2(3x−7))=22x−65
(4)(x)+(4)(2(3x−7))=22x+−65(Distribute)
4x+24x+−56=22x+−65
(4x+24x)+(−56)=22x−65(Combine Like Terms)
28x+−56=22x−65
28x−56=22x−65
Step 2: Subtract 22x from both sides.
28x−56−22x=22x−65−22x
6x−56=−65
Step 3: Add 56 to both sides.
6x−56+56=−65+56
6x=−9
Step 4: Divide both sides by 6.
6x = -9

If 46 people can fit into 64 square teet. Which proportion should you use to estimate how many people are in a 600
square foot area?
Answer:
431.25 approximately 431
Step-by-step explanation:
one way of calculating it would be to get the measure per one person which would be equal to 46 / 64 = 0.7 people in one square feet
then multiply 0.7 by the total distance = 431.25 approximated to 431
Add an apple orchard, small bags contain 7 apples. Alexa and her family bought 91 apples for a party. How many small bags did they buy? I need the problem solved out thanks
In this problem, we'll need to divide the number of apples by the amount of apples in a small bag. This will leave us with the number of small bags needed for the amount of apples.
91 / 7 = 13
Therefore, Alexa and her family bought 13 small bags of apples.
A message can follow different paths through servers on a network. The sender’s message can go to one of five servers for the first step; each of them can send to five servers at the second step; each of those can send to four servers at the third step; and then the message goes to the recipient’s server.
a. How many paths are possible?
b. If all paths are equally likely, what is the probability that a message passes through the first of four servers at the third step?
Answer:
Number of way s= N=100
The probability that it passes through first of four servers at the third step is 0.25
Step-by-step explanation:
The total number of possible ways can be found out by multiplying the possibilities so the possibilities at the
1st stage is 5
2nd stage is 5
3rd stage is 4
4th stage is 1
So Number of way s= N= 5*5*4= 100
This can be solved by drawing a tree diagram as well.
Now the probability of finding the that a message passes through the first of four servers at the third step.
There are five paths
And we have to find the probability of four
So 5C1*5C4/100= 0.25
The probability that it passes through first of four servers at the third step is 0.25

Answer: B) Profit per shirt goes from $10 to $15
================================================
Explanation:
Focus on the two points (2,0) and (3,10). The slope of the line through these points is
m = (y2-y1)/(x2-x1)
m = (10-0)/(3-2)
m = 10
Meaning the profit per shirt for this line is $10 per shirt.
----------
Now move onto the other line. Focus on the points (9,40) and (11,70)
m = (y2-y1)/(x2-x1)
m = (70-40)/(11-9)
m = 15
The profit per shirt has gone up to $15 per shirt
Answer:
I would personally say that his profit per shirt increases
Step-by-step explanation:
- he only made 10 after selling 7 shirts : can't be (• #1)
- they tell you that it's a profit function: so can't be (• #3)
- he spent 25 after he hit 50: can't be (• #4)

Use the Pythagorean Theorem to find the length of the leg in the triangle shown below. The figure shows a right triangle with one leg marked 20. The hypotenuse is marked 52.
Answer:
48
Step-by-step explanation:
The Pythagorean Theorem is:
[tex]a^2+b^2=c^2[/tex]
where [tex]a[/tex] and [tex]b[/tex] are the legs of the right triangle. [tex]c[/tex] is the hypotenuse of the triangle.
In this right triangle, we know that one leg is 20 and the hypotenuse is 52. Therefore,
[tex]a=20[/tex]
[tex]c=52[/tex]
Since we don't know the other leg, we can leave it as [tex]b[/tex]. Substitute the values into the theorem.
[tex]20^2+b^2=52^2[/tex]
Evaluate the exponents first.
⇒ 20²=20*20=400
⇒ 52²= 52*52= 2704
[tex]400+b^2=2704[/tex]
Since we want to find [tex]b[/tex], we must isolate [tex]b[/tex]. First, subtract 400 from both sides of the equation.
[tex]400-400+b^2=2704-400[/tex]
[tex]b^2=2704-400[/tex]
[tex]b^2=2304[/tex]
[tex]b[/tex] is being squared. The inverse of a square is a square root. Take the square root of both sides of the equation.
[tex]\sqrt{b^2}=\sqrt{2304}[/tex]
[tex]b=\sqrt{2304}[/tex]
[tex]b=48[/tex]
The length of the other leg is 48

Find the sum 46 +47 +48 +49+...+138 + 139.
Answer:
8695
Step-by-step explanation:
Took forever on calculator but I did it!
Answer:
8695
Step-by-step explanation:
There is a formula for adding all integers from 1 to some integer n.
[tex] 1 + 2 + 3 + ... + n = \dfrac{n(n + 1)}{2} [/tex]
In other words, to add all integers from 1 to an integer, multiply the integer by the next greater integer and divide by 2.
For example, what is
1 + 2 + 3 + 4 ?
Multiply 4 by the next integer, 5, and divide by 2.
(4 * 5)/2 = 20/2 = 10
Check: 1 + 2 + 3 + 4 = 3 + 3 + 4 = 6 + 4 = 10
We see that the formula works.
Now we need to apply that formula to this problem, but there's a little more to it.
If the problem were
1 + 2 + 3 + ... + 138 + 139, then we'd apply the formula and that would be it.
In this problem, though, we don't start the sum at 1. We start the sum at 46.
The trick here is to add all integers from 1 to 139, and then we subtract the sum of all integers from 1 to 45, so we are left with only the sum of the integers from 46 to 139.
Sum of integers from 1 to 139:
[tex] 1 + 2 + 3 + ... + 139 = \dfrac{139(139 + 1)}{2} = \dfrac{139(140)}{2} = 9730 [/tex]
Sum of integers from 1 to 45:
[tex] 1 + 2 + 3 + ... + 45 = \dfrac{45(45 + 1)}{2} = \dfrac{45(46)}{2} = 1035 [/tex]
Now we subtract the sum to 45 from the sum to 139.
46 + 47 + 48 + ... 138 + 139 = 9730 - 1035 = 8695

Resolve the vector into components. 1. A vector starting at the point Q = (4, 6) and ending at the point P = (1, 2).
2. A vector starting at the point P = (1, 2) and ending at the point Q = (4, 6).
Answer:
1. Horizontal component = -3 units
Vertical component = -4 units
2. Horizontal component = 3 units
Vertical component = 4 units
Step-by-step explanation:
If a vector M, starting at point A = (a, b) and ending at point B = (c, d) is given, then the vector can be resolved into x and y components as follows;
M = AB
Where;
AB = B - A
AB = (a, b) - (c, d)
AB = (a-c, b-d)
AB = (a-c)i + (b-d)k
Therefore, a-c and b-d are the x and y components of the vector M.
(1) Let the vector be M:
Starting point of M = Q = (4, 6)
Ending point of M = P = (1, 2)
So,
M = PQ
Where;
PQ = Q - P
PQ = (1,2) - (4,6)
PQ = (1-4, 2-6)
PQ = (-3, -4)
Therefore,
M = PQ = -3i - 4j
The x and y components of M are therefore, -3 and -4 respectively.
(2) Let the vector be M:
Starting point of M = P = (1, 2)
Ending point of M = Q = (4, 6)
So,
M = PQ
Where;
PQ = Q - P
PQ = (4,6) - (1,2)
PQ = (4-1, 6-2)
PQ = (3, 4)
Therefore,
M = PQ = 3i + 4j
The x and y components of M are therefore, 3 and 4 respectively.
Note: The x and y components are also called the horizontal and vertical components respectively.

Answer:
−3b /8
Step-by-step explanation:
Answer:
b + 11 = 11 + b
Step-by-step explanation:
Combine like terms. Note that because you are adding for all terms, you can technically disregard the parenthesis:
3 + (b + 8) = b + 3 + 8 = b + 11
3 + (8 + b) = 3 + 8 + b = 11 + b
b + 11 = 11 + b (True).

A student dropped a textbook from the top floor of his dorm and it fell according to the formula s(t) = −16t 2 + 8√t , where t is the time in seconds and s(t) is the distance in feet from the top of the building.What was the average speed of the fall? Use the fact that the pencil hit the ground in exactly 2.8 seconds. Round your answer to 2 decimal places.
Answer:
-29.61m/sStep-by-step explanation:
Given the distance of fall of the student in term of the time t expressed by the equation s(t) = −16t² + 8√t, to get the average speed of fall of the pencil after 2.8 secs, we will need to differentiate the given function first since Velocity is the change in distance of a body with respect to time i.e
V = d(s(t))/dt
s(t) = −16t² + 8t^1/2
V = -32t+1/2(8)t^(1/2 - 1)
V = -32t+4t^-1/2
The average speed of the fall Using the fact that the pencil hit the ground in exactly 2.8 seconds, will be gotten by substituting t = 2.8 into the resulting equation.
V = -32t+4(2.8)^-1/2
V = -32t+4/√2.8
V = -32+4/1.6733
V = -32+2.391
v = -29.61m/s
Hence the average speed of the fall is -29.61m/s
The average speed of the fall is -29.61m/s
Calculation of the average speed:[tex]V = d(s(t))\div dt\\\\s(t) = −16t^2 + 8t^{1/2}\\\\V = -32t+1/2(8)t^{(1/2 - 1)}\\\\V = -32t+4t^{-1/2}[/tex]
Now here t = 2.8 seconds
So,
[tex]V = d(s(t))\div dt\\\\s(t) = −16t^2 + 8t^{1/2}\\\\V = -32t+1/2(8)t^{(1/2 - 1)}\\\\V = -32t+4t^-1/2[/tex]
V = -32+2.391
v = -29.61m/s

(Plzzz someone help with this)
Answer:
Step-by-step explanation:
A). Yes. If we rotate shape I by 90° clockwise about the origin shape I will overlap shape II.
Coordinates of one point of figure I are A(-1, 3).
After rotation 90° clockwise,
(x, y) → (y, -x)
Following this rule,
A(-1, 3) → A'(3, 1)
It clearly states that figure I will overlap figure II.
B). No. because length of the quadrilateral I is different from the length of the quadrilateral given in figure III while width are same.
Both are different quadrilaterals.
C). Yes. If the figure I is reflected over x-axis, we get figure III.
D). Yes. By the translation of figure I by 3 units right and 4 units down we get image figure V.
Rule followed for the translation,
(x, y) → (x+3, y-4)
An equivalent fraction to 5/16 is
a. 5/32
b. 10/32
c.1/2
d. 10/16
Answer:
B is the answer..................
==================================================
Explanation:
Multiply top and bottom of the original fraction by 2
[tex]\frac{5}{16} = \frac{5*2}{16*2} = \frac{10}{32}[/tex]
Or you could go in reverse to divide each part of 10/32 by the GCF 2
[tex]\frac{10}{32} = \frac{10\div 2}{32\div 2} = \frac{5}{16}[/tex]
-------------------
Another alternative is to use your calculator to find the decimal version of each answer choice
5/32 = 0.15625
10/32 = 0.3125
1/2 = 0.5
10/16 = 0.625
And compare these results with 5/16 = 0.3125
Both 5/16 and 10/32 have the same decimal value 0.3125, which makes them equal.
