Final answer:
The inequality that describes the problem is x ≥ 120.
Step-by-step explanation:
To determine the inequality that describes the problem, we need to compare the amount of concrete ordered to the amount needed to fill the basketball court. Given that one bag of concrete fills 0.5 cubic yards and the school needs 60 cubic yards of concrete, we can set up the inequality as follows:
x * 0.5 ≥ 60
Where x represents the number of bags of concrete ordered. To solve for x, we can divide both sides of the inequality by 0.5:
x ≥ 120
Therefore, the inequality that describes the problem is x ≥ 120, meaning the school must have ordered at least 120 bags of concrete to fill in the basketball court.
