Practice makes perfect

Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase is at least, so we can identify that the inequality symbol should be≥.

The distance of the race,d , is at least 6 miles. The distance of the race,d ≥ 6 miles On the left-hand side, we have our variable d. On the right-hand side, we have a constant. Putting these sides together, we have a complete inequality. The distance of the race,d ≥ 6 miles d ≥ 6
