Answer:
K = 8.3 repeating or 8 1/3
Step-by-step explanation:
3k - 5 = 20
Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )
3k/3 = k
25/3 = 8.3 repeating or 8 1/3
K = 8 1/3 or 8.3 repeating.
Answer:
![\boxed{m = -2}](https://tex.z-dn.net/?f=%5Cboxed%7Bm%20%3D%20-2%7D)
Step-by-step explanation:
![0 = 4+4(m+1)](https://tex.z-dn.net/?f=0%20%3D%204%2B4%28m%2B1%29)
Resolving Parenthesis
![0 = 4+4m + 4](https://tex.z-dn.net/?f=0%20%3D%204%2B4m%20%2B%204)
![0 = 4m+8](https://tex.z-dn.net/?f=0%20%3D%204m%2B8)
Subtracting 8 to both sides
![-8 = 4m](https://tex.z-dn.net/?f=-8%20%3D%204m)
![4m = -8](https://tex.z-dn.net/?f=4m%20%3D%20-8)
Dividing both sides by 4
m = -8/4
m = -2
