Together the pets weighed 40 pounds but the dog is four times as much as the cat. How much did the dog weigh?

Answer:
8 pounds
Step-by-step explanation:
Let’s take d as dog and c as cat
So
D+c=40
And c=4d
Let’s substitute “c” as 4d
d+4d=40
5d=40
d=8
The dog weighs 8 pounds and cat weighs 2 pounds
Hope this helps
