like write a situation using these numbers

Here is one as an example:
The amount of illuminated tracer ammuntion an aircraft gun uses is once round per ten total rounds per mission, plus twenty-three. What is the algebric expression that expresses the number of tracer rounds used per mission as a function of n rounds shot?

Sure! Here's a real-world situation represented by each of the given expressions:

1. Expression: n + 7
Situation: Let's say you have n number of apples, and you receive 7 more apples. The expression n + 7 represents the total number of apples you would have.

2. Expression: 5n
Situation: Imagine you are organizing a charity event where each participant needs to bring n number of cans of food. The expression 5n represents the total number of cans collected if you have 5 participants.

3. Expression: 1/4n
Situation: Suppose you have a cake that is divided into n equal parts. The expression 1/4n represents the number of cake slices you would have if you take one-fourth of the total number of parts.

4. Expression: 2n - 12
Situation: Let's say you want to buy n number of concert tickets, and each ticket costs $12. The expression 2n - 12 represents the total cost of the tickets after applying a $12 discount.

5. Expression: n/10 + 23
Situation: Consider a marathon race where each runner completes n number of kilometers. The expression n/10 + 23 represents the total distance in kilometers traveled by a runner, taking into account that the first 23 kilometers are already fixed.

These examples illustrate how each algebraic expression can be associated with real-world situations.
