Final answer:
A real-world problem that represents x is greater than or equal to 0.25 could be measuring the height of a growing plant. We set up an inequality to find the number of days it takes for the plant to reach a height greater than or equal to 1 cm.
Step-by-step explanation:
A real-world problem that represents x is greater than or equal to 0.25 could be measuring the height of a growing plant. Let's say the plant grows at an average rate of 0.25 cm per day. We want to find how many days it takes for the plant to reach a height greater than or equal to 1 cm.
Let's set up an inequality: height ≥ 0.25 × number of days. We can solve this inequality to find the number of days when the plant reaches a height greater than or equal to 1 cm.
For example, if x represents the number of days, and x ≥ 4, it means the plant takes at least 4 days to reach a height of 1 cm or more.
