The answer is 75 and since you have to round it up to the nearest tenth the answer would be 80.

Step-by-step explanation:

You first have to add all the score numbers: 60, 65, 70, 75, 80, 85, 90

Then, you will get 525

Now, divide that by how many scores there are which is 7 and you get 75

Finally, 75 rounded to the nearest tenth is 80!

You're very welcome!!!

Good night!!

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
