You can put this solution on YOUR website! A 20 foot board is cut into two pieces whose lengths are in the ration of 7 to 3. Find the length of the longer piece.
------------------------------------------
7 to 3 is the same as 7x to 3x where 7x is the longer piece.
-----------------
Equation:
7x + 3x = 20 ft
10x = 20
x = 2
---
longer piece = 7x = 7*2 = 14 ft.
