Answer:
![x = \frac{82}{3}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B82%7D%7B3%7D)
Step-by-step explanation:
- let
be that number
![\frac{3x}{4} = \frac{41}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B4%7D%20%3D%20%5Cfrac%7B41%7D%7B2%7D)
- multiply both sides by
![\frac{3x}{4} * 4 = 4 * \frac{41}{2} \\3x = \frac{41 }{2} * 2 * 2\\3x = 41 *2 \\3x = 82 \\](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B4%7D%20%2A%204%20%3D%204%20%2A%20%5Cfrac%7B41%7D%7B2%7D%20%5C%5C3x%20%3D%20%5Cfrac%7B41%20%7D%7B2%7D%20%2A%202%20%2A%202%5C%5C3x%20%3D%2041%20%2A2%20%5C%5C3x%20%3D%2082%20%5C%5C)
![\frac{3x}{3} = \frac{82}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%20%3D%20%5Cfrac%7B82%7D%7B3%7D)

The first one, the opposite of any negative number is the same number but positive...and vise versa.
20 kg remaining in bag 1.
40 kg remaining in bag 2.
When you are rounding to the nearest tenth, you only look at the number right to the tenths which in this case is 5, so you round up the 6 to a 7, which will be.
