- x + 57 = 116
- x = 116 - 57
- x = 59
11.
- y = 180 - 112 = 68
- x= 180 - 2*68 = 44
12.
- 4x + 10 = 180 - 2*40
- 4x + 10 = 100
- 4x = 90
- x = 90/4
- x = 22.5

Each class receives the same amount of pizza because the unit rates are the same
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
Answer:
8
Step-by-step explanation:
Each movie costs $4 since the bill increased by $4 when the customer watched a movie.
$29 - $25 = $4
Create an equality using this information. Solve for x.
25 + 4x > 60
(25 + 4x) - 25 > (60) - 25
4x > 35
(4x)/4 > (35)/4
x > 8.75
Since the bill must stay under $60, round the answer down. The customer can watch 8 movies with the given price range.
