Kenny's backpack wwighs 27 pounds he has 9 books with him that each weigh the same amount when he gets to school he gives chelsea 2 books and puts 3 away in his locker how much does Kenny's backpack weigh now

12 pounds

Step-by-step explanation:

27/9=3, so each book weighs 3 pounds

Chelsea takes 2 books, or 6 pounds

3 books, or 9 pounds, go in the locker

9+6=15

27-15=12, so his backpack weighs 12 pounds

12

Step-by-step explanation:

First you find out how much each backpack weighs. For the singular unit you do 27/3 which equals 9. Then it says he gives someone 2 of his books and puts 3 in his locker. That means 5 books are coming out of the bag. 9-5 would equal 4. Then you would times each of the books by 3. That would be 4x3 to get 12.
