A ten-foot-long board is cut into three pieces. The second piece is half as long as the first. The third piece is 4 feet longer than the second. How long is the first piece?
Let's say the second piece is x ft long The first piece is 2x ft long The third piece is x+4 ft long All of the pieces should add up to 10ft x+2x+x+4=10 4x= 6 x=1.5ft The first piece is 2x ft long=3 ft long
