Barbara use distributive property to write an expression that is equivalent to 7d+63. Her work is shown below. The greatest common factor is 7 so 7d +63=7(d+63)
What was Barbara’s error?
A-Barbara wrote(d+63) Instead of(63d)
B-Barbara wrote (d+63) Instead of (d+9)
C-Barbara wrote (d-+63) instead of (d+56
D-Barbara wrote (d+63) instead of (10d)

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.

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
