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?

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!

The answer is a 5/20 because if u add all of the marbles there are 20 and there are 5 red marbles so 5/20 is the answer mark as brainliest

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
