Answer:

1. 9 hours 2. $377 3. 48 hours 4. 235 feet

Explanation:

In all cases below, let x represent the variable sought for.

1: 2x/5=3.6,

x=5/2 *3.6=9 hours

2. x-83=294

x=83+294=377

3. x+x/3=4x/3=64

x=64*3/4=48 hours

4. If the gardenview hotel's height is x, then (x+17)/2 will be the height of the Plaza Hotel.

The combined height will be x + (x+17)/2 = 361 feet

Multiplying by 2 across board,

2x+x+17=722

3x+17=722

3x =722-17=705

x=705/3=235m
