We know that Juliana is x, her sister is 2 years older, her mother is 3 times older than the sister and the uncle is 5 years older than the mother. To find out how old is Uncle Rich, we do:

Juliana = x

Sister = 2 * x = 2x

Mother = 2x * 3 = 6x

Uncle Rich = 6x + 5

So the expression representing Rich's age is 6x + 5
