My teacher took away a blue ribbon in study island i asked another teacher to reset my math in studyisland and the blue ribbon reappeard

Answer 14

I agree. @wmj259 The first equation must be x + y = 425.

Answer 15

If you decide to make a formula then the formula would need to be 2 * Kathryns score less 70 points of Micheals

Answer 16

Mihael's score(y) = 70 less(- 70) than 2 times Kathryn's score(2x)
