Mrs. Hamilton tallies her students test grades in the table below. What percent of the class received an A or a B?

The correct answer would be 30%

Hope this helps!

Mark me brainliest if I'm right :)

J. 40%

Step-by-step explanation:

12 students received an A or B. There are 30 students.

12/30=0.40

=40%

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
