How do you solve the inequality h - 2.7 ≤ 7?

Back

Add 2.7 to both sides to get h ≤ 9.7.

Front

What is the solution to the inequality 8x < 48?

Back

Divide both sides by 8 to get x < 6.

Front

When graphing an inequality, what does a closed dot represent?

Back

A closed dot represents that the number is included in the solution (used for ≤ or ≥).

Front

What does an open dot represent when graphing an inequality?

Back

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

Front

How do you represent the situation: The room can hold a maximum of 400 people, and there are already 134 people?

Back

The inequality is x + 134 ≤ 400.

Front

What is the solution to the inequality r - 12 ≥ 17?

Back

Add 12 to both sides to get r ≥ 29.

Front

What is the first step in solving the inequality x - 5 < 10?

Back

Add 5 to both sides to get x < 15.
