Not equivalent to any of the given expressions.
Step-by-step explanation:

Hence,
is not equivalent to any of the given expressions.
A, because 59-56= 3.
Others are distributed on a larger scale. 11-6=5 for B, 6-0=6 for C, 8-1=7 for D
Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
y=40
a line is 180 degrees and the other side is 70 that means 110 =2y+x so x=30 then you fill in the x. 2y+30=110 you subtract 30 from 110 and get 80 then divide 80 by 2 and get 40
