!oh select all the equations where m= 4 is a solution choose 3 answers: a) 13 = 9 + m b)7- m = 3 c) 15 = 11m d) 5 = m + 2 e) 20 divide m =5

A,B,E

Step-by-step explanation: substitute the value 4 for m in each of the equations and check if it is true.

Example:

A. 13=9+m

13=9+4

13=13 so this is a solution

C. 15=11m

15=11*4

15=44 this is not true so it is not a solution

answer: plz put a pic in so i can answer it

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°
