there are 43 ribbions. the number of blue ribbions was 2 less than the number of white ribbions. the number of red ribbions was 3 more than the number of white ribbions.how many of each kind of ribbion was awarded

  • algebra -

    b = the number of blue ribbions

    w = the number of blue ribbions

    r = the number of red ribbions



    b = w - 2

    r = w + 3


    w + b + r = 43

    w + w - 2 + w + 3 = 43

    3 w - 2 + 3 = 43

    3 w + 1 = 43

    3 w = 43 - 1

    3 w = 42 Divide both sides by 3

    w = 42 / 3

    w = 14


    b = w - 2 = 14 - 2 = 12


    r = w + 3 = 14 + 3 = 17



    14 white ribbons

    12 blue ribbons

    17 red ribbons
