Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Jerry and Malia, both teachers, are adding books to their class libraries. Jerry's classroom started out with a collection of only 12 books, but he plans to purchase an additional 4 books per week. Malia's library started out with 36 books, and she has enough money in her budget to purchase another 1 book per week. At some point, the two teachers' libraries will contain the same number of books. How many books will each class have? How many weeks will that take?

The two teachers' libraries will each have in weeks.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
