The correct answer is D. 1,136
This is because when you divide 3,000 by 140 (the total amount of people surveyed) you get about 21. Then multiply 21 by the number of people who chose N. Monroe (53). That answer is 1,136.

What is the equation that could be used to solve for x?
pashok25 [27]

Answer:

x=32

Step-by-step explanation:

I believe the angles are supplementary so you could use the equation:

2x+8 + 3x+22 = 180

5x+30=180

5x=160

x=32
