Answer:
x = 41
Step-by-step explanation:
(2x+20) + (2x-4) = 180 degrees
4x+16 = 180 degrees
4x = 164
x = 41
The two sides are supplementary and add up to 180 degrees.

Answer:
D
Step-by-step explanation:
The answer is d, because a represents adults, and c represent children. It's $45 per adult, so $45a, and $30 per child, so $30c. a+c is equal to 10, because that's how many tickets were purchased. $45a+$30c=345, because $345 is the total amount spent on tickets.
