20 ! which expression is equivalent to − 1 /6 y+ 1 /3 1/6 ( y + 1/3 ) - 1/6 ( y + 2 ) - 1/6 ( -y + 2) 1/6 ( -y + 2) ! do not quess! explain ur answer

The last one is correct.
1/6 (-y+2)
-1/6y+2/6     2/6=1/3
-1/6y+1/3

The answer is 1/6 ( -y + 2)

The answer is option c.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
