Add 8 to both sides. Subtract x from both sides. Now you have 3x=18. Now divide 3 by 18. Your answer is x=6
Let's see what to do buddy...

Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
![(n - 2) \times 180](https://tex.z-dn.net/?f=%28n%20-%202%29%20%5Ctimes%20180)
Our figure has 5 sides ;
So , sume the interior angles of it equals :
![(5 - 2) \times 180 = 3 \times 180 = 540 \\](https://tex.z-dn.net/?f=%285%20-%202%29%20%5Ctimes%20180%20%3D%203%20%5Ctimes%20180%20%3D%20540%20%5C%5C%20)

Step (2)
First look at the photo which I post.
According it we have :
![(180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\](https://tex.z-dn.net/?f=%28180%20-%20x%29%20%2B%20120%20%2B%2085%20%2B%20%282x%20-%2010%29%20%2B%2090%20%3D%20540%20%5C%5C%20)
![2x - x + 475 - 10 = 540](https://tex.z-dn.net/?f=2x%20-%20x%20%2B%20475%20-%2010%20%3D%20540)
![x + 465 = 540](https://tex.z-dn.net/?f=x%20%2B%20465%20%3D%20540)
Subtract the sides of the equation minus 465 :
![x = 540 - 465](https://tex.z-dn.net/?f=x%20%3D%20540%20-%20465)
![x = 75](https://tex.z-dn.net/?f=x%20%3D%2075)

The 16th flip has a 50% chance of landing white. It doesn't matter what the first 15 flips were, the probability for each flip is 1-in-2 (black or white). That would be fraction 1 over 2, or 1/2
Answer:
=6
Step-by-step explanation:
Total money = 150 + 95 + 210 + 45 + 55 + 165 = $720
Total months is 6
Mean = 720 / 6 = $120
