The number of cats to dogs at the pet store was 5 to 8. If there were 184 dogs at the store , how many cats were there?

There were 115 cats at the pet store.

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

Since the number of cats to dogs at the pet store was 5 to 8.

The proportion is cats / dogs = 5/8

For 184 dogs = x / 184

Where x is the number of cats:

5/8 = x/184

Solving for x:

5/8 (184) =x

115 =x

There were 115 cats at the pet store.

Feel free to ask for more if needed or if you did not understand something.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
