Is there a question you need help on?
X=2 because -2x+2 Is canceled then add 2x to 6x which is 8x then add 11 to -11 that’s canceled then add 11 to 5 which is 16 then divide 16 by 8x and x =2
It's commutative property because of the order

Answer: 75 cars (choice C)</h3>
Explanation:
x = 13 represents 1 PM since it is 13 hours after 12:00 AM midnight.
Fast forward another 3 hours and we get to x = 13+3 = 16 to represent 4 PM
Mark 16 on the x axis. Then draw a vertical arrow upward until you get to the parabola. From there, draw a horizontal line to the left until reaching the y axis. See the diagram below.
You should arrive between y = 60 and y = 90. A good estimate is to find the midpoint
midpoint = (a+b)/2 = (60+90)/2 = 150/2 = 75
We estimate that about 75 cars are expected to be parked at 4 PM.
