Solve each of the following equations for the given variable. If correct I will mark you as the best answer

1) 3(2x + 5)=3

2) 9+9x = 2(x + 1)

3(2x+5)=3      6x+15  = 3                         6x =  -12       x =-2

9+9x=2x+2             9x-2x= 2-9        7x=  -7          x=-1

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°
