Hello!
![\large\boxed{x = 3}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%20%3D%203%7D)
2x + 1 = 5x - 8
Solve by subtracting both sides by 2x:
2x - 2x + 1 = 5x - 2x - 8
1 = 3x - 8
Add 8 to both sides:
1 + 8 = 3x - 8 + 8
9 = 3x
Divide both sides by 3:
9/3 = 3x/3
x = 3
Okay - so 12pi/6 = 360. We need to make 31pi/6 between 0pi/6 and 12pi/6 in order to obtain the reference angle. So let's do that.
31pi/6 - 12pi/6 = 19pi/6
19pi/6 - 12pi/6 = 7pi/6
The reference angle in radians is 7pi/6, but it wants degrees - so we convert to degrees using 180/pi.
7pi/6 * 180/pi = 210 degrees
Anne will need 9 cans of white paint.
the ratio of white to blue: 3:2
multiply by 3 because 6/2 equals 3.
white to blue: 9:6
Hope this helps!
