MR SPIDER HAS 7 TIMES AS MANY FLIES AS HE DOES BEETLES. ALTOGETHER HE HAS 48. HOW MANY FLIES AND HOW MANY BEATLES DOES MR SPIDER HAVE?
To write an expression for the given situation, you need to identify the key elements.
For the first scenario, Susan had 24 stamps and used some to mail letters. Let's assume she used "x" number of stamps. To determine the expression, you can subtract the number of stamps used from the initial number of stamps Susan had.
Expression: 24 - x
For the second scenario, Nancy had 23 books, and her dad bought her some more books. Let's assume her dad bought "y" number of books. Nancy was left with all the books her dad bought, but 3 books were not given to her. To determine the expression, you can subtract 3 from the sum of the books bought.
Expression: (y + 23) - 3
Remember to replace the variables (x and y) with actual values if provided in the question.
