Problema Solution
The 16-foot board in the illustration has been cut into two parts, one three times as long as the other. How long is each part?
Answer provided by our tutors
let
x = the length of the shorter part
3x = the length of the longer part
x + 3x = 16
4x = 16 divide both sides by 4
x = 4 ft
3*4 = 12 ft
the lengths of the two parts are: 4 ft and 12 ft.
