Answer:
![\frac{3}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B14%7D)
Step-by-step explanation:
Total Students = 28
Brown Hair = 22
NOT Brown Hair = 28 - 22 = 6
The probability of an event is the number of that event divided by total number.
So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:
P(NOT BROWN) = 6/28
Reducing, we get:
P(NOT BROWN) = 3/14
Answer:(x+1)/x=6,then x=1/5 or 0.2

Answer:
![D. (3,-1)](https://tex.z-dn.net/?f=D.%20%283%2C-1%29)
Step-by-step explanation:
![x + y = 2 \: \: \: \: \: \: ..(1) \\ 2x - y = 7 \: \: \: \: ..(2)](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%202%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20..%281%29%20%5C%5C%20%3C%2Fp%3E%3Cp%3E2x%20-%20y%20%3D%207%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20..%282%29)
from equation 1 we get,
![x = 2 - y](https://tex.z-dn.net/?f=x%20%3D%202%20-%20y)
now,
![put \: \: \: \: x = 2 - y \: \: \: in \: (2)](https://tex.z-dn.net/?f=put%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20x%20%3D%202%20-%20y%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20in%20%5C%3A%20%282%29)
we get,
![2(2 - y) - y = 7 \\ 4 - 2y - y = 7 \\ 4 - 3y = 7 \\ - 3y = 7 - 4 \\ - 3y = 3 \\ \\ y = \frac{3}{( - 3)} \\ \\ y = - 1](https://tex.z-dn.net/?f=2%282%20-%20y%29%20-%20y%20%3D%207%20%5C%5C%204%20-%202y%20-%20y%20%3D%207%20%5C%5C%204%20-%203y%20%3D%207%20%5C%5C%20%20-%203y%20%3D%207%20-%204%20%5C%5C%20%20-%203y%20%3D%203%20%20%5C%5C%20%20%5C%5C%20y%20%3D%20%20%5Cfrac%7B3%7D%7B%28%20-%203%29%7D%20%20%5C%5C%20%20%5C%5C%20y%20%3D%20%20-%201)
now,
![put \: \: \: \: y = - 1 \: \: \: \: in \: (1)](https://tex.z-dn.net/?f=put%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20y%20%3D%20%20-%201%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20in%20%5C%3A%20%281%29)
we get,
![x + ( - 1) = 2 \\ x - 1 = 2 \\ x = 2 + 1 \\ x = 3](https://tex.z-dn.net/?f=x%20%2B%20%28%20-%201%29%20%3D%202%20%5C%5C%20x%20-%201%20%3D%202%20%5C%5C%20x%20%3D%202%20%20%2B%201%20%5C%5C%20x%20%3D%203)
hence, the value of x = 3 and y = (-1)
3 times 10 is 30
30 minus 5 is 25
25 is the answer
I hope it helps!! Have a great day
