Nine plus four (Answer= 12)
A number, c, minus four (Can’t solve this)
a number, x, times a number, y, (answer=xy)
Answer:
a. ![Odds = \frac{3}{7}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7B3%7D%7B7%7D)
b. ![Odds = \frac{7}{3}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7B7%7D%7B3%7D)
Step-by-step explanation:
Given
![n(Black) = 7](https://tex.z-dn.net/?f=n%28Black%29%20%3D%207)
![n(Grey) = 2](https://tex.z-dn.net/?f=n%28Grey%29%20%3D%202)
![n(White) = 1](https://tex.z-dn.net/?f=n%28White%29%20%3D%201)
![n(Total) = 10](https://tex.z-dn.net/?f=n%28Total%29%20%3D%2010)
Solving (a): Odds against winning
Since, the arrow must stop at black, then
The odds against winning is calculated as thus:
![Odds = \frac{n(Total) - n(Black)}{n(Black)}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7Bn%28Total%29%20-%20n%28Black%29%7D%7Bn%28Black%29%7D)
![Odds = \frac{10 - 7}{7}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7B10%20-%207%7D%7B7%7D)
![Odds = \frac{3}{7}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7B3%7D%7B7%7D)
Solving (b): Odds in favor of winning
Since, the arrow must stop at black, then
The odds is calculated as thus:
![Odds = \frac{n(Black)}{n(Total) - n(Black)}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7Bn%28Black%29%7D%7Bn%28Total%29%20-%20n%28Black%29%7D)
![Odds = \frac{7}{10 - 7}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7B7%7D%7B10%20-%207%7D)
![Odds = \frac{7}{3}](https://tex.z-dn.net/?f=Odds%20%3D%20%5Cfrac%7B7%7D%7B3%7D)
Answer:
What is the question??
Step-by-step explanation:

Answer:
Given the inequality: ![5x < 16 +x](https://tex.z-dn.net/?f=5x%20%3C%2016%20%2Bx)
Subtraction property of equality states that you subtract the same number to both sides of an equation.
subtract x from both sides we get;
![5x -x < 16 + x -x](https://tex.z-dn.net/?f=5x%20-x%20%3C%2016%20%2B%20x%20-x)
Simplify:
![4x < 16](https://tex.z-dn.net/?f=4x%20%3C%2016)
Divide both sides by 4 we get;
![x < 4](https://tex.z-dn.net/?f=x%20%3C%204)
Therefore, the solution set for the given inequality is, ![(-\infty, 4)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%204%29)
