he made 3 times as many swans as cranes.he made 5 times more cranes than dragons.in all, he made 25 origami figures. how many of each did he make ?

  • math - ,

    s = 3 c
    c = 5 d

    s + c + d = 25

    3c + c + c/5 = 25

    4.2 c = 25

    c = 25/4.2 etc

    Dragons = X,
    Cranes = (X + 5X),
    Swans = 3(X + 5X).

    X + (X + 5X) + 3(X + 5X) = 25,
    X + 6X + 18X = 25,
    25X = 25,

    X = 25/ 25 = 1 Dragon.

    Cranes = 1 + 5*1 = 6.

    Swans = 3(1 + 5*1) = 3*6 = 18
