Waynes homework is to solve at least 20 questions from his textbook so far he has completed 9. Write an inequality to show how many more he needs to complete

9+q ≥ 20
q ≥ 11

thanks

The inequality to show how many more questions Wayne needs to complete is:

q ≥ 11,
where q represents the number of questions Wayne still needs to complete.

To determine the inequality that shows how many more questions Wayne needs to complete, let's break it down step by step.

First, we know that Wayne has completed 9 questions so far. We can represent this with the number 9.

Next, we need to represent the number of questions he still needs to complete. Let's call this number "q".

Therefore, the total number of questions Wayne has completed and still needs to complete is 9 + q.

Finally, we want to write an inequality to show that Wayne needs to complete at least 20 questions in total. This means that 9 + q needs to be greater than or equal to 20.

Combining all of this, the inequality can be written as:

9 + q ≥ 20

To solve this inequality for q, we can isolate q by subtracting 9 from both sides:

q ≥ 20 - 9

Simplifying this expression, we get:

q ≥ 11

Therefore, Wayne needs to complete at least 11 more questions to reach a total of 20 questions.
