Question

At the pet fair, Darlene's dog weighted 5 times as much as Leah's dog. Together, the dogs weighted 84 pounds. How much did each dog weight? Complete the bar model. Write an equation and solve.

Please help.

Answer 1

let x = Darlene's dog's weight
let y = Leah's dog's weight 

x = 5y
x + y = 84 

so, 5y + y = 84, which means 6y = 84   so, y = 84/6 = 14
x = 5(14) = 70    

Darlene's dog = 70 lbs, Leah's dog = 14 lbs.

Answer 2

6×n=84
n=14
5×14=70
Darlene's dog weighs 70 pounds. Leah's dog weighs 14 pounds.

I know this is correct because I have the exact same question in my math book and our teacher corrected it! Hope I helped you today! : )
