Mabel scores 19 points more on her pre-algebra test than Nancy. Phoebe scored 10 points less on her pre-algebra test than Nancy.
If Phoebe scored 23 points, how many points did Mabel score? Please help me with this problem guys. Im doing homework. Thanks! Whoever answers it will get 34 points.
M = N + 19 N - score of Nancy ; M - score of Mabel, P - score of Phoebe: P = N - 10 P = 23 23 = N - 10 N = 23 + 10 N = 33 M = 33 + 19 M = 52 Mabel scored 52 points.
