15. 
Add "g" on both sides

Multiply 5 on both sides to get x by itself
x = 5(a + g)
x = 5a + 5g
18. a = 3n + 1
Subtract 1 on both sides
a - 1 = 3n
Divide 3 on both sides to get n by itself
= n
21. M = T - R
Add "R" on both sides to get "T" by itself
M + R = T
24. 5p + 9c = p
Subtract "5p" on both sides
9c = p - 5p
9c = -4p
Divide 9 on both sides to get "c" by itself
c =
or c = 
27. 4y + 3x = 5
Subtract "4y" on both sides
3x = 5 - 4y
Divide 3 on both sides to get "x" by itself
x = 
x = 
Answer:
Q= 5c
Step-by-step explanation:
Answer:
The slope is m=2.5 $/movie
Step-by-step explanation:
The slope of the graph could be found using any two points
y
and the equation for slope of a line, which is

So, we select the points
y
, and we replace the values in the equation for slope,

And in this case, represents the cost to rent one movie.
Answer:
x = 10
Step-by-step explanation:
Use CPCTC (Corresponding parts of congruent triangles are congruent).
Set the ratios:

First, simplify. Combine like terms:

Next, cross multiply.

Isolate the variable, x. Divide 6.5 from both sides of the equation:

Check:

Plug in 10 for x (Your answer). Cross multiply, then simplify:



(True).

U first convert it into improper fraction :
2 7/10
=20+7/10
=27/10
=2.7 ...
Hope it helps !!!
