Atest contains multiple choice questions and short answer questions. the short answer questions are worth more than the multiple choice questions. one student answers 17 multiple choice questions correctly and four short answer questions correctly and scores 71 points. another student answers 15 multiple choice questions correctly and eight short answer questions correctly, and scores 85 points. if you create a system of equations to represent these test results, and you use elimination to solve it, which equation below could be used to determine how much the multiple choice questions are worth?

step-by-step explanation:

this is not a question

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.
