Final answer:
The correct inequality to represent the number of pages left in a book that has less than 240 pages is x < 240. This aligns with the information provided and indicates that there are between 0 and 239 pages left to read.
Step-by-step explanation:
To determine how many pages are left to finish reading the book if the book has less than 240 pages, you would use an inequality. The appropriate inequality to show that the number of pages left to read, which we can call x, is less than 240 pages would be x < 240. This means that the number of pages still to be read is somewhere between 0 and 239 pages.
Considering the options provided in the question:
- A. x > 240 is incorrect because it means more than 240 pages, which contradicts the information given that the book has less than 240 pages.
- B. x < 240 is the correct answer as it aligns with the book having less than 240 pages.
- C. x ≤ 240 is incorrect because it means x can be exactly 240, which is not less than 240 pages.
- D. x ≥ 240 is also incorrect as it indicates that x is greater than or equal to 240, which again, is not less than 240 pages.
