Which expressions are equal to -5/8 - (-1/8-1/2)

-5/8 - (1/8 - 1/2) Parentheses first in order of operations

-5/8 - (1/8 - 4/8 = -3/8)

-5/8 - (-3/8) Two negatives make a positive; two minuses make a plus

-5/8 + 3/8 = -2/8 = -1/4

expression #3 is not equivalent. the others are.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
