Move k to the other side to isolate d.
So we will get 3d = 8c - 8d - k
Now divide both sides by 3 to isolate d.
So d = 8/3c - 8/3d - k/3
According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
<u>Explanation:</u>
Let the number of dogs be d and the number of cats be c
If the ratio of dogs to cats is 49:28, then the ratio of d : c would be

On reducing the fraction, we get

It is shown that the number of cats is reduced to 20.
So, let the number of dogs after sometime be x
Thus,

After cross multiplying we get:
140 = 4x
x = 35
According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
Answer:
X= 12.5
Step-by-step explanation:
U do the inverse which is 114.50-14.50=100
