Juliana is x years old. her sister is 2 years older than her. her mother is 3 times as old as her sister. her uncle rich is 5 years older than her mother. write and simplify an expression representing rich's age.

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
