All you needed to do was put 9 over one and multiply by 4/6 and you get 36/6

**Answer:**

Let X be the number.

Twice the number would be 2x

The difference between the two, would be subtraction, so you would subtract 4 from 2x

The equation becomes 2x-4 = 16

Now solve for x:

2x-4 = 16

Add 4 to each side:

2x = 20

Divide both sides by 2:

x = 20/2

x = 10

The number is 10.

Take the angle then multiple them by what ever needs to be, then finish it. and sorry not in geometry abd i am not good with angles.

Hey there,

Total = 860

Section 1 = 270

Section 2 = x + 150

Section 3 = x

Section 2 + 3 = 860 - 270

= 590

x+150+x = 590

x+x = 590 - 150

2x = 440

x= **220**

Thus there were **220** spots in Section 2

Hope this helps ^_^
