The work of a student trying to solve the equation 4(2x β 1) = 11 + 3x + 5 is shown below:
Step 1: 4(2x β 1) = 11 + 3x + 5
Step 2: 8x β 4 = 16 + 3x
Step 3: 8x + 3x = 16 β 4
Step 4: 11x = 24
Step 5: x = 2.18
In which step did the student first make an error and what is the correct step?
Step 2: 8x β 1 = 16 + 3x
Step 2: 8x β 8 = 6 + 3x
Step 3: 8x β 3x = 16 + 4
Step 3: 8x + 3x = 16 β 8

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
