Step-by-step explanation:
The answer key for the "Did you hear about" math worksheet can typically be found in the appendix or at the end of the book that contains the worksheet. Some textbooks provide a partial answer key for selected problems, while others may provide a comprehensive answer key for all problems.
For example, the OpenStax math textbook series offers an Answer Key at the end of the book, which includes answers for selected exercises. You may need to have a verified instructor account to access some answer keys and additional resources.
It's important to note that answer keys are usually designed to guide the student towards the correct analysis and approach, rather than providing direct numerical answers. They may provide a range within which the answer is expected to lie, helping students catch any errors in their approach.
