Some kids were on a field trip.  They were split into groups of 7.  There were fewer than 9 groups.  Which inequality can determine the total number of kids?

• 7x ≤ 9

• 7x > 9

• x/7 > 9

• x/7 < 9

When do we switch the inequality symbol?

• when multiplying or dividing by a negative number

• when adding or subtracting a negative number

• when the answer is a negative number

• When there is a negative number in the problem

Using division, solve the inequality: 3z < 9

• z < 3

• z = 3

• z > 3

• z < 9

Answer explanation

To solve the inequality 3z < 9, divide both sides by 3. This gives z < 3. Therefore, the correct choice is z < 3.
