How does 1-3/8 = 5/8?

Step-by-step explanation:

1 is also known as 8/8, because anything that has all the parts to it is a whole.

Meaning, we can change this equation into 8/8-3/8, which makes it much easier.

With that, if you subtract the numerators, 8-3,  you get 5. In other words, you are subtracting three "pieces" from the eight "pieces". You end up with 5 of the original 8 "pieces", or 5/8.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
