Answer:

A. 10x=350

B. 35 inches

Step-by-step explanation:

So the first piece is x, and the second is 3 times as long, so the second is 3x, and the third pice is twice as long has the second piece which is 3x, so third piece is 6x. The total is 350 inches, so x+3x+6x=350. Simplify that so you get 10x=350. Divide both sides by 10, and you get x=35 inches. Hope that helps!
