Johnny and mona work in a bakery.
johnny sells 14 boxes of almond cookies. each box has the same number of cookies. let a represent the number of almond cookies in a box.
mona sells 28 boxes of chocolate cookies. each box has the same number of cookies. let b represent the number of chocolate cookies in a box.
johnny writes 14a+28b as an expression to show the total number of cookies that he and mona sold.
which of the following expressions is equivalent to johnny's expression?
14(a+b)
14(a+2b)
14a+(2b)
28(a+b)

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.
