Alexia spent 3 minutes working on each of her math problems and 4 minutes on each of her science problems. her homework took her more than 60 minutes to complete. the boundary line for the inequality 3x + 4y > 60 is shown. which statement could be true in this situation? alexia completed 8 math problems and 9 science problems. alexia completed 4 math problems and 6 science problems. alexia completed 20 math problems and 10 science problems. alexia completed no math problems and 15 science problems.

The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60

Therefore, our answer is correct.
