Problema Solution
Amys dog weighs 5 times as much as her hamster. Together they weigh 20 pounds. How much does the dog weigh?
Answer provided by our tutors
let 'x' represent the weight of her hamster, then '5x' represents the weight of her dog
20 = x + 5x
x = 20/6 = 3 1/3
20 - 3 1/3 = 16 2/3
Amy's hamster weighs 3 1/3 pounds, her dog weight 16 2/3 pounds
