1 answer

Question 1: The correct equation for the relationship between the cat's age (c) and the dog's age (d) is:

C) c = d + 3

Question 2: To find the age of Jamie's dog when her cat is 7 years old, plug in the value of c = 7 into the equation c = d + 3:

7 = d + 3

Subtract 3 from both sides:

d = 4

Therefore, the age of Jamie's dog when her cat is 7 years old is 4.

Answer: 4
