Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
Eight quarters is equal to two dollars. Two one-dollar bills are also equal to two dollars. Therefore, choosing either option would result in the same amount of money.

Answer:
131 and 49
Step-by-step explanation:
Supplementary angle means 180° when all angles are added together.
First angle: (x + 82)
Second angle: x
(x + 82) + x = 180
2x + 82 = 180
2x = 98
x = 49
First angle: 49 + 82 = 131°
Second angle: 49°
