Mackenzie is organizing textbooks on her bookshelf. She has an English textbook, a biology textbook, and a history textbook. How many different ways can she line the textbooks up on her bookshelf (Fundamental Counting Principal)

the correct answer is x/3+10≥32

hope this !

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.
