Subtract 5 from both sides: x > 2.

Front

How do you solve the inequality 2k > 18?

Back

Divide both sides by 2: k > 9.

No, because 9 is not greater than 9.

Front

When graphing an inequality, what does an open dot represent?

Back

An open dot represents that the number is not included in the solution (used for < and >).

Front

When graphing the inequality x > 20, how would you represent it on a number line?

Back

Draw a number line, place an open dot at 20, and shade to the right.
