Inequality Test

At the local 5k race, runners 10 and under or runners 65 and above start the race after the others. What compound inequality represents the situation?

• 10 ≤ x ≤ 65
• x ≥ 10 or x ≤ 65
• x ≤ 10 or x ≥ 65
• 10 < x < 65

Your family needs 2 gallons of water this week, but you don’t want to buy any more than 8 gallons. Write an inequality representing the possible gallons of water you could buy this week.
