Answer:
-20
Step-by-step explanation:
If we get -5 points for each question you answer incorrectly, and we answer 4 questions incorrectly, than we can simply multiply -5 by 4 to get -20.
Answer:
![m=\frac{2A-kn}{k}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2A-kn%7D%7Bk%7D)
Hence, option C is true.
Step-by-step explanation:
Given the expression
![A=\frac{k}{2}\left(m+n\right)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bk%7D%7B2%7D%5Cleft%28m%2Bn%5Cright%29)
Solving for 'm'
![A=\frac{k}{2}\left(m+n\right)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bk%7D%7B2%7D%5Cleft%28m%2Bn%5Cright%29)
Flip the equation
![\frac{k}{2}\left(m+n\right)=A](https://tex.z-dn.net/?f=%5Cfrac%7Bk%7D%7B2%7D%5Cleft%28m%2Bn%5Cright%29%3DA)
Expanding by applying the distributive law: ![a\left(b+c\right)=ab+ac](https://tex.z-dn.net/?f=a%5Cleft%28b%2Bc%5Cright%29%3Dab%2Bac)
![\frac{1}{2}km+\frac{1}{2}kn=A](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dkm%2B%5Cfrac%7B1%7D%7B2%7Dkn%3DA)
Add (-1)/2 × kn to both sides
![\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dkm%2B%5Cfrac%7B1%7D%7B2%7Dkn%2B%5Cleft%28-%5Cfrac%7B1%7D%7B2%7Dkn%5Cright%29%3D%5Cleft%28-%5Cfrac%7B1%7D%7B2%7Dkn%5Cright%29%2BA)
simplify
![\frac{1}{2}km=-\frac{1}{2}kn+A](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dkm%3D-%5Cfrac%7B1%7D%7B2%7Dkn%2BA)
Divide both sides by k/2
![\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7Dkm%7D%7B%5Cfrac%7Bk%7D%7B2%7D%7D%3D%5Cfrac%7B-%5Cfrac%7B1%7D%7B2%7Dkn%2BA%7D%7B%5Cfrac%7Bk%7D%7B2%7D%7D)
![m=\frac{2A-kn}{k}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2A-kn%7D%7Bk%7D)
Therefore,
![m=\frac{2A-kn}{k}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B2A-kn%7D%7Bk%7D)
Hence, option C is true.
