Answer:
cost of each video game = $5.50
cost of each movie = $4.25.
Step-by-step explanation:
Let m represent cost per movie
g represents cost per video game.
Create two equations to represent the total cost Tammy rented movie and video games in each month, and solve simultaneously for each variable:
First month:
=> equation 1
Second month:
=> equation 2
Multiply equation 1 by 4, and multiply equation 2 by 2 to derive:
4 ×
2 ×
=> equation 3
=> equation 4
Subtract equation 4 from equation 3
You'd have:
- 4g = - 22
Divide both sides by -4
g = 5.5
Thus, the cost of each video game = $5.50.
Substitute g = 5.5 in equation 1 and solve for m.
Subtract 16.5 from each side
Divide both sides by 2
Thus, cost of each movie = $4.25.
The answer is 240. Associative property
(a*b)*c= a(b*c). Hope this helps!!

Answer:
6x-8
Step-by-step explanation:
Subtract 8 from 4 to get −4.
13x−4+6x−13x−4
Combine 13x and 6x to get 19x.
19x−4−13x−4
Combine 19x and −13x to get 6x.
6x−4−4
Subtract 4 from −4 to get −8.
6x−8
Cost divided by number of items equals each items cost
20/16= 1.25
$1.25
