Answer:
well the middle on is 3
Step-by-step explanation:
1. 462.25 × 24 × 60 = 665640
2.
![100000 \leqslant 75x - 25x + 10000](https://tex.z-dn.net/?f=100000%20%5Cleqslant%2075x%20-%2025x%20%2B%2010000)
![100000 \leqslant 50x + 10000](https://tex.z-dn.net/?f=100000%20%5Cleqslant%2050x%20%2B%2010000)
![90000 \leqslant 50x](https://tex.z-dn.net/?f=90000%20%5Cleqslant%2050x)
![1800 \leqslant x](https://tex.z-dn.net/?f=1800%20%5Cleqslant%20x)
![x \geqslant 1800](https://tex.z-dn.net/?f=x%20%5Cgeqslant%201800)
3. you have to sub first so
![3 + \frac{x}{2} = 10](https://tex.z-dn.net/?f=3%20%2B%20%5Cfrac%7Bx%7D%7B2%7D%20%3D%2010)
given
x/2 = 7
subtract
x=14
multiplication
