Question

A 25-foot board is cut into two pieces. Four times the length of the shorter piece is 5ft more than the length of the longer piece. Find the length of the shorter piece.

a.19ft
b. 4ft
c. 6ft
d. 15ft
e. 10ft

Answer 1

s + l = 25----> s + l = 25

4s = l + 5---->4s - l = 5

--------------

5s = 30

s = 6 ft, l = 19 ft

The correct answer is C.
