Fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.

Idiot.
Y=-3/2x+4
The slope is -3/2, since Kerry traveled three feet and only went down 2.

Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18
If the elevator stopped at the 18th floor and she got in and went 14 floors down and got off, she got off on the 4th floor
