What is the solution to the equation?
2/3a - 1/6 = 1/3
Answer:
a = 3/4
Step-by-step explanation:
2/3a - 1/6 = 1/3
Multiply each side by 6 to clear the fractions
6*(2/3a - 1/6) = 6*1/3
Distribute
4a - 1 = 2
Add 1 to each side
4a -1+1 = 2+1
4a = 3
Divide each side by 4
4a/4 = 3/4
a = 3/4
Answer:
a= 1/3
Step-by-step explanation:

Answer:
15
Step-by-step explanation:
y= 7(15)+50
y= 105+50
y=155
y=10x+5
y=10(15)+5
y=150+5
y=155
I don't understand this
plz answer 3,4 and 5
Answer:
3. Since it asked us to write question 3 in the from y=mx + c
m is the gradient
c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).
Now to find m.
Pick points on the line
Say (1,6) and (2,3)
Gradient = m = y2 - y1/(X2 - X1)
x1 = 1
y1 =6
x2 = 2
y2 = 3
Substituting into that formula
m = 3 - 6/2 - 1
m= -3/1
m= -3.
Since we've gotten what we need
y=mx + c
Y= -3x + 9.
4. 4x + 2y = 12
Rearranging by making y subject to suit the eqn...y=mx + c
you have
m is the gradient and c is the intercept.
2y = -4x + 12
Divide through by 2
y= -2x + 6
y=mx + c
By comparing...
m==gradient = -2
c== Intercept = 6
5). Doing the same thing we did above
-6x + 3y =21
Making y subject
3y = 6x + 21
Divide through by 3
y= 2x + 7
y=mx + c
m==gradient =2
c==Intercept =7.
Hope this helps.
Have a great day!

I need help with find the area of the other shapes. Like you can give me an example of the width and lenth like this (8:7) and I'll put a pic of what I've got so far and I need you to do what I did please.I really need help.
You must include the following items: • At least 10 shapes in which you can calculate the area (label the dimensions for each shape in feet 1 cm=3.25feet) o 2 rectangles o 1 rhombus o 3 triangles (1 must include a fractional base) o 2 trapezoids (1 base must be a decimal) o 1 pentagon o 1 irregular polygon in which you’ll have to decompose into smaller shapes. And if my pic ain't clear enough sorry.
Answer:

Given f(x) and g(x) = f(x + k), use the graph to determine the value of k.
Answer:
f(x)=x+4
g(x)=x+10
g(x)=f(x+k)
x+10=x+k+4
x-x+10-4=k
6=k
k=6

Can I get help? And please give the steps to how you got your answer.
Answer:
D
Step-by-step explanation:
First, plot the points they gave you onto a graph (shown in the attached image). The slope is the rise (units up or down from a given point) over the run (units left or right from a given point).
So the slope is 6/4 because to get from the red point to the blue point, you rise 6, and run 4. And from blue to red you rise (remember rise goes up or down) 6 and run 4. 6/4 can be simplified to 3/2 so D is your answer :)
A right triangle has legs of 30m and 40m. What is the PERIMETER of the triangle?
choices:
A.) 120m
B.) 70m
C.) 1200m
D.) 50m
Answer:
A
Step-by-step explanation:
We know that we are dealing with a right triangle. Look at the legs given to us, 30m and 40m. That looks familiar doesn't it? In fact, this quite resembles the 3-4-5 special right triangle.
We can simply scale the legs by 10 to find the last side of the triangle.
[tex]3*10=30\\4*10=40[/tex]
and therefore, the last side of the right triangle must be:
[tex]5*10=50[/tex]
Great! Now we have all the sides of the right triangle. We just have to add them up:
[tex]30+40+50=120[/tex]
Therefore, the perimeter of the triangle is 120m. A.
I hope this helps! Let me know if you have any questions :)
Can I get help...plz give steps
Answer:
C)
Step-by-step explanation:
First, multiply the 2 factors that add up to 8.
1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.
Divide and multiply 2 by 8 and 1/3. Then, we solve for y.
y = 2/3x - 4
Hope this helps!

Consider the 720 permutations of the numbers 1, 2, 3, 4, 5, 6. In how many of these permutations do exactly 3 of the numbers end up in the positions where they started?
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with 2.
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.

The coach of the field hockey team can spend at most $475 on new team uniforms. The coach will order the uniforms online and pay a mailing cost of $11. If each uniform costs $29, how many uniforms can the coach order?
Answer:
16
Step-by-step explanation:
475-11-29n=0, so 464= 29 n. so n would be 16
Answer:
16 uniforms
Step-by-step explanation:
his budget:475
mailing cost:11
remaining budget:475-11=464
now,
cost of one uniform= 29
no of uniform he can order is= 464÷29= 16

Pls help me so I can pass
Answer:
The slope of the line is constant. This is because all straight lines have a constant slope. The slope of this line is 1/3. When you use the legs to measure, the horizontal legs of the triangle, they increase in length by 3 units from the previous triangle. The vertical legs of the triangle also increase by 1 with each added triangle. Both of these observations support that the slope of the line is a constant 1/3.

Answer:
C
Step-by-step explanation:
1. π ≈ 3.1415. π + 10 ≈ 13.1415.
2. Find the square root of 20. It is about 4.4721. 4.4721 + 1/2 (or .5) = 4.9721
3. The square root of 100 is 10.
4. Order them.
5. It is most obvious that the answer to [tex]\sqrt{20\\}[/tex] + 1/2 is first. The square root of 100 is ten, so that goes second because pi + 10 is greater than 10. (pi + 10 goes last)
6. [tex]\sqrt{12} + 1/2, \sqrt{100}, \pi + 10[/tex]
