(x+y) / 2 =7
multiply both sides by 2
x+y=14
3x=.5y
divide both sides by .5
6x=y
plug 6x in for y
x+(6x)=14
simplify
7x=14
divide both sides by 7
x=2

Sarah received a gift in a rectangular box with a volume of 240 in3. If the base of the box was 20 in2, how tall was the box?
Murrr4er [49]
V = l * w * h
240 = 20* h
divide both sides by 20
12 = h
height = 12 inches
