During one term, rachel took 2 mathematics test. her mean score was75. she scored 12 points more on the first test than on the second test. how many points did she score on the second test

she scored 69 points on the second test.

Step-by-step explanation:

Let x represent the number of points that she scored on the second test.

She scored 12 points more on the first test than on the second test. It means that the number of points that she scored on the first test would be

x + 12

Therefore, the total number of points that she scored on both tests would be x + 12 + x = 2x + 12

Her mean score for both tests was 75

Mean = total points scored/number of tests

Therefore,

75 = (2x + 12)/2

2x + 12 = 150

2x = 150 - 12 = 138

x = 138/2 = 69
