    @clairvoyant1 How many feet in a yard? How many inches in a yard? With that info, we can get started on this problem.

    The idea is to change the given measurements into yards so that when we multiply to get the volume, what we get will be in cubic yards.

    Cross multiply. 3*(9x) = 1* (2x + 5)

    3*(9x) = 1* (2x + 5) 27x = 2x + 5 --> Solve for x.

    Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. f(x) = quantity x minus seven divided by quantity x plus two. and g(x) = quantity negative two x minus seven divided by quantity x minus one.
