Which expression represents the sum of 2x-5y and x+y

Which expression represents the sum of and ?

Answer :                                              

We have to find the sum of the given two expressions, so we will add the like terms together.

or simplify it as

This becomes, .

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°
