Answer: C
Explanation:
In our inequality, we have 5x-19<16. Notice the inequality is strictly less than. That means it does not include 16 at all. We denote this on a number line or graph by an open circle. This tells us that we can eliminate B and D because those are closed circles. Notice the difference between A and C. A is going towards the right and greater. C is going to the left and smaller. Less than means smaller, so C is the answer.
