Question

There are 6 times as many dogs as cats. If the total number of dogs and cats is 21. How many dogs are there

Answer 1

Answer: There are 18 dogs.

Step-by-step explanation:

Let x be the number of cats.

Given : There are 6 times as many dogs as cats.

Number of dogs = 6x

If the total number of dogs and cats is 21, then we have

$x+6x=21\\\\\Rightarrow\ 7x=21$

We divide both sides by 7 , we get

$x=3$

Now, number of cats = 3

Number of dogs = 6(3)=18

Hence, there are 18 dogs.

Answer 2

18, because cats would be 3, and then the dogs would be 6 times that, which would be 18.  18 + 3 = 21.
