    1. What is the value of "y" for the given value of x and z
    y= x +z x=3 z=15
    Substituting x=5 and z=15 into the expression for y, we obtain
    y=x+z=5+15=20
    So y=20.

    2. Rewrite each fraction with the Lowest Common Denominator
    4/15, 2/9, 3/5 43/36 + 3/5 + 1/4
    The lowest common denominator for the first three fractions is 45. So we ...

    Solution Summary
