8packs of baseball cards 3 fewer packs of hockey cards than football cards 17 packs in all

Number of packs of football cards = 6 , hockey cards = 3 , baseball cards = 8

Step-by-step explanation:

Number of packs of baseball cards = 8

Let the number of packs of football cards = x

Number of packs of hockey cards = x - 3

Total number of packs = 17

=> 8 + x + (x-3) = 17

=> 8 + 2x -3 = 17

=> 2x = 17 - 5 = 12

=> x = 12/2 = 6

So the number of packs of football cards = 6

Number of packs of hockey cards = 6 - 3 = 3

Validation:

Adding all the packs together:

Baseball + Hockey + Football

= 8 + 3 + 6 = 17

This satisfies the requirement that total number of packs is 17.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
