What is the value of x in the equation ? 13x - 2(8+5x) = 12 - 11x

x=2

Step-by-step explanation:

13x - 2(8+5x) = 12 - 11x

The first step is to distribute the -2

13x -2*8 -2*5x = 12-11x

13x -16-10x = 12-11x

Combine like terms

3x-16 = 12-11x

Add 11x to each side

3x+11x -16 = 12-11x+11x

14x-16 = 12

Add 16 to each side

14x-16+16 = 12+16

14x=28

Divide by 14

14x/14 =28/14

x =2

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
