Question

When Theresa got her puppy, it weighed 6 ponds less than 2/3 of its weight now. If the puppy weighed 4 pounds when she first received himnwhat is her puppys weight now

Answer 1

15 lb

Explanation:

let the current weight of the puppy be X, the initial weight of the puppy is 4lb or
`(2)/(3)X-6\ lb`, (6 lb less 2/3 X) .

#We equate the current weight to the initial weight to determine X:

`4\ lb=(2)/(3)X-6\ lb\\\\10 \ lb=(2)/(3)X\\\\X=15`

Hence, the current weight of the puppy is 15 lb
