Sara got 37 out of 50 questions right, and Tony got 29 out 40, who did better, Tony or Sara?

Sara did better.

Step-by-step explanation:

To find who did better, I calculated their overall percentage each scored on their test.

For Sara:

37÷50=0.74

Multiply the decimal by 100 to get a percentage of 74%.

For Tony:

29÷40=0.725

Multiply the decimal by 100 to get a percentage of 72.5%

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
