At a pet store, it costs $5 to wash a cat and $7.50 to wash a dog. Last week, the store made $60 from washing cats and dogs. If 6 cats were washed, write and solve a linear equation to find how
many dogs were washed.

4 dogs

Step-by-step explanation:

If you let x equal the number of cats washed and y equal the number of dogs washed then you can make the equation:

5x+7.5y=60

You can then put the number of cats washed into the equation:

5(6)+7.5y=60

30+7.5y=60

7.5y=30

y=4

So 4 dogs were washed

eve and marks ratios are equivalent

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
