Answer:
Ric is 7 years old.
Step-by-step explanation:
Choose variables for everyone's ages. I'll choose for Ric's age, for Paul's age, and for Tom's age.
Since Ric's age is half of Paul's age, we can write this equation:
Since Tom is two years younger than Paul, we can write this equation:
Since the sum of all their ages is 33 years, we can write this equation:
Since we know and in terms of , we can replace them in the equation above as follows:

Now that we know that , we can substitute 14 for in the equation:
Ric is 7 years old.

Answer:
17n+9 feet
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L +W)
P = 2((4.5n +9) +(4n -4.5)) = 2(8.5n +4.5)
P = 17n +9
The perimeter of the rectangle is 17n +9 feet.
