This is tricky because it has a lot of variables, but we just have to treat this problem normally.

separate y from p + n (feel free to check that you can do this by multiplying y out again and seeing that we have the same thing as before)

divide p + n on both sides

Answer:

140/5 = 28 points per game
504/12 = 42 miles per gallon
8.97/3 = 2.99 per bag

An angle in radians marks out the same number of radiuses on the circle. That's one thing that often makes radians so neat to work with.
The angle in the middle of this circle is 2 radians. So the arc ' S ' is 2 times the length of the circle's radius.
In my head, I get S = 14 units , but you should check it out.
3w + 8 - w = 4w - 2(w - 4)
2w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
0 = 0
Therefore, option b is an identity.
