1 answer:
frosja888 [35]3 years ago
8 0

Answer:

35

Step-by-step explanation:

First let's find g(7):

g(7) = 2(7)-11

g(7) = 14-11

g(7) = 3

Now we find f(g(7))

f(3) = 3(3²)+7(3)-13

f(3) = 3(9) +21-13

f(3) = 27+21-13

f(3) = 35

Sarah has 86% in science, 72% in English, 93% in World Studies,87% in french,93% in music, 100% in health and 80% in math. What
Serga [27]

Average: about 87%

Her english grade affects her average because it is the lowest out of all of the grades which brought her average grade down.

not sure about this: To bring her average higher, she should probably try more in english or study. (not sure about this one)

Step by Step:

Add up all of her scores:

86 + 72 + 93 + 87 + 93 + 100 + 80

it equals 611

Since we added up 7 scores, we divide 611 by 7

611 divided by 7 is 87.285...

So her average is about 87%
