Answer 1

Answer 2

C

Answer 3

all answers

Answer 4

She was able to knit 45 rows in 50 minutes, and 15 rows in x minutes. Find x then add it to 50. That would be your "m". Your "r" has to be 60, because that was her total. This means that your answer is either A or D. Since A wouldn't make sense, i would go with D. Do you understand?

Answer 5

B, and D

Answer 6

"All answers" cannot be correct because A and B can't both be correct at the same time.

Answer 7

That is just what I think it could be.
