Pumping iron: 10x+90=0
Fit for life: 15x+50=0
Set them equal to each other. 10x+90=15x+50. Solve for x. Subtract 50 from both sides, get 10x+40=15x, then subtract 10x from both sides, getting 40=5x. Divide 5 from both sides to isolate x, x=8. After 8 months the two gyms will cost the same.

Answer:
x=144
Step-by-step explanation:
Use the polygon formula (n-2) * 180 where n is the number of points
This polygon has 8 points
(8-2)*180 = 6 * 180 = 1080
136+124+141+158+116+129+132+x=1080
x=144
Answer:
Distance between the points (-3,1) and (1, -2),
