10^2 is 100. 247 divided by 100 is 2.47. 2.47 + 2.47 is your answer. Im lazy, add yourself. 4.94
Here you go. Hope you get this.
Answer:
x=12
Step-by-step explanation:
Step-by-step explanation:
Okay, so...
The Median of a trapezoid is directly in the middle. For some weird mathimatical reason you won't ever need to know unless it's on an exam or you become a math major, its midsegment is the average of the top length and the bottom length.
In other words,
EF = ( BC + AD ) / 2
So for part 1, we can use that equation to find x.

![4x-18=[(x+12)+(3x-4)]/2](https://tex.z-dn.net/?f=4x-18%3D%5B%28x%2B12%29%2B%283x-4%29%5D%2F2)
- Simplify within parentheses.
![4x-18=[x+12+3x-4]/2](https://tex.z-dn.net/?f=4x-18%3D%5Bx%2B12%2B3x-4%5D%2F2)
![4x-18=[x+3x+12-4]/2](https://tex.z-dn.net/?f=4x-18%3D%5Bx%2B3x%2B12-4%5D%2F2)
![4x-18=[4x+8]/2](https://tex.z-dn.net/?f=4x-18%3D%5B4x%2B8%5D%2F2)




Part 2 is a lot easier now. All we have to do is plug in 11 for x.

Answer:
Part I: x = 11
Part II:
Answer: 2598.8
Solution:
Step one: 49•12.80 = 627.2 (the amount that people under 16 payed)
Step two: 155-49=106 (the amount of people over 16)
Step three: 106•18.60=1971.6 (the amount of money that people over 16 payed)
Step four: 627.2+1971.6=2598.8 (the total amount of collected money from tickets)
