20 + 20 + 10 + 25 = 75
75 - 2 = 73
P ( blue for the third selection ) = 20/73
Use midpoint formula:
8+2/2 ,-3+9/2
= 5,3.
The second option
1. x+12
2. x-8
3. 3*x
4. x^(2)+5
5. (x/2)+7
6. 4*(x+6)
7. (1/2)*x
8. 2x+8
9. x^(2)+3
10. (x/3)+12

1. 2-50
2.20/4=5
3.100-50=50
4.three times two then add to four equals ten
5. the diffrence of eight and four
If a triangle equals 180, than what you want to do is add all of the numbers together. 33+21+28= 82.
After that what you want to do is subtract that by the total of the triangle "180"
180-82=98.
I believe 98 is the answer
