That's not enough information to calculate your grade from.
-- You've told us the scores you have in things that go together
to make up (35 + 5 + 25) = 65% of your grade.
-- We don't know your scores in the things that make up the other
35% of your grade.

Answer:
2y² -4y +5
Step-by-step explanation:
First you need to find the sum of y²+5y-1 and 3y²-2y+4
(y²+5y-1) + (3y²-2y+4) => y²+3y²+5y-2y-1+4
=4y²+3y+3
Next is to subtract 2y²+7y-2 from the sum calculated above in order to find the algebraic expression asked in the exercise
4y²+3y+3 -(2y²+7y-2) => 4y²-2y²+3y-7y+3+2
=2y² -4y +5
Therefore, the algebraic expression asked must be 2y² -4y +5
2/5
because if you turn 3 1/5 into an improper fraction that 16/5 divided by 8/1 equals 16/40 which when simplified equals 2/5
X= 51 is the answer you need to remember that since they share a straight line you add the together to get 180 which is half a circle
