Mitchel is half as old as damon, and damon is 3 years older than tiffany. if x represents tiffany's age, what expression represents mitchel's age?

m = (3t)/2, or (3/2)t

Step-by-step explanation:

Represent the unknowns as follows:

d:  Damon's age; t:  Tiffany's age; and m:  Mitchel's age.

Then:  m = d/2; d = 3t.  Replace "d" in the first equation by "3t" from the second equation:

m:  Mitchel's age:  m = (3t)/2, or (3/2)t.
