If i got a 35% out of 20 questions and im going to get half credit in the 13 problems i got wrong what is going to be my percent going to end up being? the test was 40% of my grade.

Step-by-step explanation:

So since each question is 5% (100/20=5)

we can do ((13*5)/2) because of half credit we divide by two

now we get 32.5% back

32.5%+35%=67.5%

unless of course of extra points on other assignments, the highest grade you can get in that class (if every other thing is a 100%) is an 87 if im not mistaken.

Step-by-step explanation:

4x+y=15 1

3x+5y=412

y=15–4x3

3 in 2

3x+5(15–4x)=41

3x+75–20x=41

3x–20x=41–75

-17x=-34

x=-34÷-17

x=2

x=2 in 1

4(2)+y=15

8+y=15

y=15–8

y=7

x=2,y=7
