What expression is equivalent to 12r-5

(24r-10)/2

Step-by-step explanation:

12r-5 Lets multiply everything by 2 since we are given nothing to simplify

24r-10 now we have to make it equivalent to 12r-5

So all we will do is put it in a fraction bar

24r-10 is the numerator and 2 is the denominator

So the final result is: (24r-10)/2

answer a & b

Step-by-step explanation:

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°
