Question 15527: A cord is 189 feet long. It is to be cut into three pieces so that the second piece is twice as long as the first, and the third is twice as long as the second. Find the length of each piece

x= first piece
2x= second piece
4x=third piece
so x+2x+4x=189
7x=189 Divide both sides by 7
gives x=27 feet
2x=54 feet
4x=108 feet
