Hello there! I am EnjoyingLife, and I hope you find my answer helpful.
First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)
Now, let's write an inequality to represent the cost of books.
We know that all books cost less than $5.
We have a sign for "less than". It's "<"
Thus,
p<5
Hope it helps!
Have an awesome day!
Good luck!

You just divided 1/2 (.5) by 10 which is .05. so the answer is 0.05 gallons
1. A) 5 (It would be B. because it does equal 4.09 but it has to be 5 because it is the greatest integer in all of them)
2. D) 10 (Just like 1. it would be B. also BUT 10 is the greatest integer you can have out of all of them)
3. A) 6 (Just like the other 2 problems at the top^ it would be C. if not for the fact it has a higher number.)
4. A) A value we can put in place of a variable (such as x) that makes the equation true.
The range would be [-4, infinity) because range is the y-value. The lowest y-value is -4. The greatest y-value goes up to infinity.
