Make a system of equations and solve for each variable.

3m+8v=53
5m+2v=26

m= movie cost
v= game cost

multiply the bottom equation by 4(combination method)

3m+8v=53
20m+8v=104. Subtract

-17m = -51
m= 3

Plug back into one of the equations

5(3)+2v=26
15+2v=26
2v=11
v=5.5

m=$3
v=$5.5

Choose the correct simplification of f to the 9th power times h to the 23rd power all over f to the 3rd power times h to the 17t
klio [65]

If you subtract 3 from 9 you get 6, so it would be f^6 and if you subtract 17 from 23 you get 6 also, so it would be h^6

f^6h^6, I believe the answer is c.

Rewrite in simplest terms: <br> 10 ( 7 g − 9 h ) − 4 h − 8 ( − h + 8 g )
Ksju [112]

Answer:

6g -86h

Step-by-step explanation:

10( 7g-9h) -4h - 8(-h + 8g)

1) First, distribute the 10 and the -8 to the terms in the parentheses next to them. Remember, don't distribute to the -4h since it is not in the parentheses.  

10( 7g - 9h) -4h - 8(-h + 8g)\\70g - 90h-4h+8h-64g\\

2) Next, combine like terms. (Any terms that have the same variables must be added together by their coefficients.)

70g - 90h-4h+8h-64g\\\\70g-64g-90h-4h+8h\\6g-86h

There are no more like terms to combine, so 6g -86h is the answer.

If EF=6 and EG=21, find the value of FG. The drawing is not to scale.
pantera1 [17]
You can find the value of FG by subtracting the value of EF from EG.

EG - EF = FG
   21 - 6 = FG
        15 = FG

The value of FG is B. 15 .
