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
