y=x/2+50
y=200, x=?
---------
- 200= x/2+50
- x/2=200-50
- x/2=150
- x=150*2
- x=300

14.I can't see the whole graph, so you need to do it yourself. Add up everyone's age and divide by the amount of people on the graph. That will give you the average.

Answer:
The increase is 1150.

Answer:
a. x is equal to 54.5
Step-by-step explanation:
The interior angles of a pentagon will add up to 540. Since it is a regular pentagon, each angle would be 108 degrees. So we can set the value of the angle to 108 and solve for x.
2x - 1 = 108
2x = 109
x = 54.5
