A number is less than 20 units away from 7 on the number line. What numbers are within these parameters?

Choose the inequality that represents the situation.

Solve the inequality.

Chose the graph that correctly illustrates the inequality.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
