2/3x - 14/3 = -2
3(2/3x - 14/3) = -2(3)
2x - 14 = -6
2x = -6 + 14
2x = 8
x = 8/2
x= 4
hope this helps :)
1/9 times 2/2=2/18
2/3 times 6/6=12/18
2/18+12/18+5/18=(2+12+5)/18=19/18=1 and 1/8
A is answer
In a circle, the internal vertical angles have a formula of

In this case, the formula would be:

We know that whole circle is 12x. And 12x is equal to 360°. When we put that into equation:


If x is 30°:

So, angle 7 is 90°.
