Question

Ali dog weighs 8 times as much as her cat. Together, the two pets weight 54 pounds. How much does Ali dog weigh?

Answer 1

dog weighs 48 pounds

Explanation:

let x be the weight of the cat, then the dog weighs 8x ( 8 times as much as dog )

sum the 2 weights and equate to 54

x + 8x = 54 ( simplify left side )

9x = 54 ( divide both sides by 9 )

x = 6

that is the cat weighs 6 pounds

and the dog weights 8x = 8 × 6 = 48 pounds
