X and (4x - 20) are supplementary angles because they add up to 180°. You can tell this because the line which they are formed on is 180<span>°.
Knowing that x + (4x - 20) = 180, you can solve for x:
</span>x + (4x - 20) = 180
(x + 4x) - 20 = 180
5x - 20 = 180
5x = 200
x = 40°

Answer: x = 40°
You would make approximate $42.50 each day. In two weeks you would make $595
Answer:
x = -20
Step-by-step explanation:
First we can rearrange the equation:
-18 = -28
2 *
- 18 = -28 * 2
The 2s canel out
x - 36 = - 56
x = -20
U count how many students were walking then multiply it by half itself
