1. There are two vertical angles. One angle is represented by 15x and the other angle 7x + 40. What is the value of x?

2. There are three supplementary angles. The first angle is 5x - 5, the second angle is
2x, and the third angle is 8x - 10. Find x.

3. There are two complementary angles. The first angle is 6x + 20 and the second angle
is 4x + 10. Find x.

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
