One number added to three times another number is 24. five times the first number added to three times the other number is 36

let “x” represent “a number”

x + 3x = 24

5x + 3x = 36

I’m not sure if this is what you may want but correct me!

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°
