1. State the missing steps and reasons to this solution of 3(x + 4) = 18.
a) 3(x + 4) = 18
b)
c) 3x + 12 - 12 = 18 - 12
d) 3x + 0 = 18 - 12
e) 3x = 18 - 12
f
h) 1x
IN
) X=2

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°

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
