Does 3(2k-5)=6(k-4)+9 have no solution of many solutions
Answer:
infinite (many)
Step-by-step explanation:
3(2k-5)=6(k-4)+9
6k-15=6k-15
since they are the same on both sides of the equal side any solution for x would work.
The equation 3(2k - 5) = 6(k - 4) + 9 has many solutions.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
3(2k - 5) = 6(k - 4) + 9
6k - 15 = 6k - 24 + 9
6k - 15 = 6k - 15
Both sides of the equation are the same.
This means,
The equation has many solutions.
Thus,
The expression has many solutions.

the length of a rectangular field three times of it's breath.if the area of the field is 675 m2, find the perimeter
with full solution
L/W = 3/1 or L = 3*W
A = L*W = (3*W)*W = 3*W^2 = 675 m^2
W^2 = (675 m^2)/3 = 225 m^2
W = sqrt(225 m^2) = 15 m
L = 3*W = 3*(15 m) = 45 m

Solve the quadratic equation by completing the square.
x^2 - 18x + 68 = 0
First, choose the appropriate form and fill in the blanks with the correct numbers.
Then, solve the equation. Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
Answer:
x = x = 9 ±[tex]\sqrt{13}[/tex] or x ≈ 12.61 or x ≈ 5.39
Step-by-step explanation:
x² - 18x + 68 Solve by completing the square.
x² - 18x = - 68
Now complete the square and add that number to both sides of the equation.
1/2 (of the coefficient of the x term)² = (1/2 · -18)² = 81 .
x² - 18x + 81 = -68 + 81
(x - 9) (x - 9) = 13 Now find the square root of both sides
[tex]\sqrt{(x - 9)(x - 9)}[/tex] =[tex]\sqrt{13}[/tex] Solve
x - 9 = ±[tex]\sqrt{13}[/tex] Solve for x
x = 9 ±[tex]\sqrt{13}[/tex]
x = 9 + [tex]\sqrt{13}[/tex] or x = 9 - [tex]\sqrt{13}[/tex]
x ≈ 12.61 or x ≈ x 5.39

Answer:
47%
Step-by-step explanation: 375 × .125 = .046875
rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.

will give brainliest if u do all parts!!!
Part A
Answers:
x+y = 125
x = y+45
---------------
Explanation:
The first equation represents Angela playing both sports a combined 125 minutes. We simply add the variables x and y to represent adding the times for soccer (x) and golf (y).
Because she plays soccer 45 minutes more compared to golf, we also have the equation x = y+45.
==========================================================
Part B
Answer: 40 minutes
---------------
Explanation:
The second equation from part A says x = y+45
Because of this, we'll replace the 'x' in the first equation with y+45 and solve for y. I'm using the substitution rule.
So,
x+y = 125
y+45+y = 125 .... replace x with y+45
2y+45 = 125
2y = 125-45
2y = 80
y = 80/2
y = 40 minutes is the amount of time playing golf per day.
==========================================================
Part C
Answer: No it's not possible.
---------------
Explanation:
We found that y = 40 earlier. Let's used this to find x
x = y+45
x = 40+45
x = 85
Therefore, Angela spends 85 minutes playing soccer everyday. It's close to 80 minutes, but not quite there. So it's not possible that she spent 80 minutes playing soccer everyday.
Another way to show this is to say x+y = 80+40 = 120 which is five minutes short of the 125 minute goal.

Answer:
Subtract 36 and 16
Step-by-step explanation:
16 + b^2 = 36
Subtract 16 from each side
16+b^2 -16 = 36-16
b^2 = 20
Take the square root of each side
sqrt(b^2) = sqrt(20)
b = sqrt(20)

Answer:
y = 50, x = 74
Step-by-step explanation:
the total degrees must equal 180. In the left triangle, we are given 80 as in of them. 180-80=100 degrees left in the triangle there are two equal angles left, so we divide 100/2 and get 50, so y=50. In the triangle on the right, there are two equal angles of 53 degrees. So 53x2=106. 180-106= 74 degrees left. x is the only angle left, so x=72

Answer:
There are no solutions.
Step-by-step explanation:
Put it in an equation
x + 5 = x − 13
Let's solve your equation step-by-step.
x + 5 = x − 13
Step 1: Subtract x from both sides.
x + 5 − x = x − 13 − x
5 = − 13
Step 2: Subtract 5 from both sides.
5 − 5 = − 13 − 5
0 = − 18

Justin worked 12 hours and 4 minutes on Saturday and 13 hours and 41 minutes on Sunday. How many hours did Justin work this weekend?
Answer:
Justin worked 25 hours and 45 minutes.
25 3/4 hours total
First add the hours together.
12 + 13 = 25
Then add the minutes together.
4 + 41 = 45
So 25 hours and 45 minutes
or
25 3/4 hours
45 minutes is also 3/4 of an hour

Find the zeros of f (x) = 8x^2 - 1.
The zeros are x = ___and x___
Answer:
x=[tex]\sqrt{2}[/tex]/4 and x=-[tex]\sqrt{2}[/tex]/4
Step-by-step explanation:
One method of solving is using the Quadratic Formula: -b ±[tex]\sqrt{b^{2}-4ac }[/tex]/2a, with a=8, b=0, and c=-1.
After plugging these values in you get -0±[tex]\sqrt{0^2-(4*8*-1)}[/tex]/2*8
After simplifying you get ±[tex]\sqrt{32}[/tex]/16
Because 32 is 2^5, you can simplify it to 4[tex]\sqrt{2}[/tex], which makes the equation ±4[tex]\sqrt{2}[/tex]/16, or ±[tex]\sqrt{2}[/tex]/4.

rewrite the equation in standard form y - 6 = -1/2 (x-5)
Standard Form: Ax + By = C
---A cannot be negative, nor can it be a decimal or fraction
y - 6 = -1/2(x - 5)
Distribute the -1/2
y - 6 = -1/2x + 5/2
Add -1/2x to both sides
1/2x + y - 6 = 5/2
Add 6 to both sides
1/2x + y = 17/2
Multiply everything by 2 to get rid of the fractions
x + 2y = 17

There are 6 yellow, 4 orange, 2 green, and five blue plastic building blocks all the same
size in a bag. What is the probability of selecting an orange, putting it back, then
а
selecting a block that is not orange.
We want to get the probability of selecting an orange, putting it back, then selecting a block that is not orange.
We will see that the probability is P = 0.1799
In the bag we have:
6 yellow blocks4 orange blocks2 green blocks5 blue blocks.For a total of 6 + 4 + 2 + 5 = 17 blocks.
First we want to find the probability of getting an orange block, as all the blocks have the same probability of being randomly drawn, the probability of randomly drawing an orange block is equal to the quotient between the number of orange blocks and the total number of blocks.
We get:
p = 4/17
Now we put the orange block back and we want to take a block that is not orange, the probability is computed in the same way:
q = (6 + 2 + 5)/17 = 13/17
The joint probability (this is, the probability of these two events happening together) is just the product of the individual probabilities.
We get:
P = p*q = (4/17)*(13/17) = 52/289 = 0.1799
