Help me please it would be appreciated

Since it is the midpoint we can say:
12x  - 1 = 8x +11
All we have do to is get all the x's alone on one side

12x - 1 = 8x + 11
12x = 8x + 12    (add both sides by 1)
4x = 12   (subtract both sides by 8x)
x = 3       (divide both sides to get what x is)

1. Jill had the following scores on quizzes. 1 quiz: 1 3 quizzes: 2 4 quizzes: 3
Irina-Kira [14]
The mean score is 3.08.

There is 1 quiz with score 1, so 1 point; 3 quizzes with score 2 for 3*2 = 6 points; 4 quizzes with score 3 for 4*3 = 12 points; 4 quizzes with score 4 for 4*4 = 16 points; and 1 quiz with score 5 for 5 points.

This is a total of 1+6+12+16+5 = 40 points.

This is out of 1+3+4+4+1 = 13 quizzes.

40/13 = 3.08
