Problema Solution
a 48-inch board is cut into two pieces. one piece is three times the length of the other. find the lengths of the two pieces
Answer provided by our tutors
let
x = the length of one piece
y = the length of the other piece
a 48-inch board is cut into two pieces
x + y = 48
one piece is three times the length of the other
x = 3y
by solving the system of equations
x + y = 48
x = 3y
we find
x = 36 in
y = 12 in
