(x-6)/2 = 8
x-6 = 16
x = 22
You can use cubes to help you write an expression and model the problem by using the cubes in replace of numbers. It should be a lot easier. Then after you finish you just have to write it down. There are other ways, but this is just one.
Answer:
Step-by-step explanation:
50% is
but we're working with 64 units, not 100. So, we must find a number that represents 50 but in 64 units.
![\frac{50}{100}=\frac{x}{64}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B100%7D%3D%5Cfrac%7Bx%7D%7B64%7D)
If you solve for x, you get:
![x=\frac{50*64}{100}\\ x=32](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B50%2A64%7D%7B100%7D%5C%5C%20x%3D32)
![\frac{50}{100}=\frac{32}{64}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B100%7D%3D%5Cfrac%7B32%7D%7B64%7D)
