A 200-centimeter-long wire is cut into three peices. The second piece is three times as long as the first. The third piece is 2 times as long as the second. How long is each piece?
Assuming the value of the first piece is x, then the equation would be this: x+3x+6x=200 Simplify, and you get: 10x=200 Solve for x: x=20 So the first piece(x) was 20 cm long The second piece(3x) was 60 cm long The third piece(6x) was 120 cm long
