A37 foot long Submarine sanwich is cut in to three piece.the shortest piece is x feet long.the second piece is twice as long as the shortest piece.the longer piece is 2 feet longer than four time the length of the shortest piece.find the length of all three piece

  • math homework -

    answer is x= 35/9

  • math homework -

    shortest piece --- x
    second piece ---- 2x
    longest piece ---- 4x+2

    x + 2x + 4x+2 = 37
    7x = 35
    x = 35/7 ,
    x = 5 , which is not your answer

    check:
    shortest = 5
    second = 10 , twice as long
    longest = 2 more than 4 times the shortest = 2+20 = 22
    and 5+10+22 = 37
