This is eazy 630=90x
divide 90 on both sides
7=x
x=in
7feet=1in

Answer:
7/19 in.
Step-by-step explanation:
Use a proportion. Let x equal the unknown model length.
model/real = (14 in.)/(38 ft) = x/(1 ft)
(14 in.)/(38 ft) = x/(1 ft)
Cross multiply.
38 ft * x = 1 ft * 14 in.
Divide both sides by ft.
38x = 14 in.
Divide both sides by 38.
x = (14 in.)/(38)
x = 7/19 in.
