At the pet fair, sams dog weighed 7 times as much as Leanne's dog. Together the dogs weighed 72 pounds. How much did each dog weigh?

Respuesta :

So, you find y is equal to 14 (Leah's dog weight). Then, x is equal to 5y, 5*14=70. So, x is equal to 70 (Darlene's dog weight.
If we call Leanne's dog x, then we can write an equation that looks like this:
7x + x = 72
Now we just need to solve it:
8x = 72
÷ 8
x = 9
So Leanne's dog weighed 9 pounds. 9 × 7 = 63, which means that Sam's dog weighed 63 pounds. Hope this helps!
