I don't exactly know what you're asking but I can give you this:
Aiden paid 22.2 $ in total
His sister paid 8.5$ in total
He paid 13.7 $ more than his sister
If the youngest is 6 and the oldest is 35 then the range equals 6 to 35.
Answer: $553.20
Step by step explanation: Since they took the price down 29% multiply the price by 1.29 to add the 29 percent back to the total amount. 428.84 * 1.29 = 553.20
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.
