Yvonne is interested in testing the effectiveness of a new flea medication on dogs, so she divided some dogs with fleas into two groups, group A and
group B. She gave group A the flea medication. Should she also give group B
the flea medication?
A. No, because group B should be the control group
B. Yes, because group B should be the control group
C. No, because group A is already the control group
D. Yes, because group A is already the control group

step-by-step explanation:

just plug in each number for x and see which ones work and don't

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

thats not a system of equations, that is a solution
