An animal shelter has 18 cats.
The shelter has 9 more cats than dogs.
Which answer choice shows the correct way to find d, the number of dogs the shelter has?
To find the number of dogs, we know that the shelter has 9 more cats than dogs. We can set up the equation:
18 cats = d dogs + 9
To isolate d, the number of dogs, we subtract 9 from both sides:
18 cats - 9 = d dogs + 9 - 9
9 cats = d dogs
Therefore, the correct way to find d, the number of dogs the shelter has, is 9.
To find the number of dogs the shelter has, we can set up a mathematical equation using the information given.
Let's say d represents the number of dogs.
The shelter has 9 more cats than dogs, so the number of cats can be represented as d + 9.
We are told that there are 18 cats in the shelter, so we can set up the equation:
d + 9 = 18
To find the value of d, we need to solve this equation.
To find the number of dogs the shelter has, we need to set up an equation based on the information given.
Let's use the variable 'd' to represent the number of dogs.
The problem states that the shelter has 9 more cats than dogs. This means that the number of cats is equal to the number of dogs plus 9.
So, we can write an equation:
Number of cats = Number of dogs + 9
Since we know there are 18 cats, we can substitute the value into the equation:
18 = d + 9
Now, we can solve for 'd'.
To find the value of 'd', we can subtract 9 from both sides of the equation:
18 - 9 = d + 9 - 9
9 = d
Therefore, the correct way to find the number of dogs the shelter has is to subtract 9 from the number of cats, which in this case is 18. So, the answer is d = 9.
