The answer is A cause if you solve the problem it will be x < 10 and A is going to the left which is less than 10 so the answer is A.

I think you are right.

4x + 20 < 40 Subtract 20 from both sides

4x < 40 - 20

4x < 20 Divide by 4

x < 20 / 4

x < 5 Somewhere very near 5 is as close as the solution gets. So at 5 you use an open circle. Because near 5 is the largest possible solution, the arrow heads left. Pat yourself on the back. These things are not easy.
