Question

This equation shows how Rocky the puppy's weight varies with age.

Answer 1

Answer:

Age of Rocky = 5 months

Step-by-step explanation:

Given that:

Equation for calculating puppy's weight

p = 3a + 2

Here,

p = weight of puppy

a = age in months

We have to find the age if the weight is 17 pounds

Putting p=17 in given equation

17 = 3a + 2

17 - 2 = 3a

3a = 15

Dividing both sides by 3

$\frac{3a}{3}=\frac{15}{3}\\a=5$

Hence,

Age of Rocky = 5 months
