Elaine is counting votes from a school election. There were 3 candidates running for president, and students either voted for 1 of those 3 or the didn't vote at all. If there are 860 students in the school and one-fourth of them voted for Serina, two-fifths of them voted for Sandra, and three tenths voted for Michelle, how many students did not vote?

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.
