Question

Write an equation to represent the problem, be sure to explain the meaning of any variables you use, Jaden dog was 5 and a half inches tall when it was a puppy, now her dog is 14 and a half inches taller than that, how tall is the dog now​

Answer 1

The dog is 20 inches tall now.

Explanation:

Given that:

Height of dog when it was a puppy =
`5(1)/(2)` inches

Height of dos now =
`14(1)/(2)` than previous height

It means that we will add this height in the height of dog when it was a puppy.

Height of dog now =
`5(1)/(2)+14(1)/(2)`

Height of dog =
`(11)/(2)+(29)/(2)=(11+29)/(2)=(40)/(2)`

Height of dog = 20 inches

Hence,

The dog is 20 inches tall now.
