How many brothers does everyone here have?
3x+15−7x=−7
Simplify:
3x+15−7x=−7
3x+15+−7x=−7
(3x+−7x)+(15)=−7(Combine Like Terms)
−4x+15=−7
Subtract 15 from both sides.
−4x+15−15=−7−15
−4x=−22
Divide both sides by -4.
−4x/−4=−22/−4
x=11/2

Answer:
h(t) = -5t + 500
Step-by-step explanation:
At time zero, the elevator is at 500 ft.
At time 5 seconds, the elevator is at 475 ft.
The difference in height is -25 ft.
The elevator traveled -25 ft (25 ft down) in 5 seconds, so it travels at a speed of 5 ft per second. Since it is traveling down, its speed is -5 ft/sec.
For each second of travel, it loses 5 ft of height.
h(t) = -5t + 500
