What is this inverse operation 1/3 + b > 3/4?

A pair of inverse operations is defined as two operations that will be performed on a number or

variable, that always results in the original number or variable. Another way to think of this is

that the two inverse operations “undo” each other. For example, addition and subtraction are

inverse operations since we can say

x x    2 2 . If we start with x, then add 2 and subtract 2,

we are left with the original starting variable x.

There are several inverse operations you should be familiar with: addition and subtraction,

multiplication and division, squares and square roots (for positive numbers), as well as cubes and

cube roots. The following examples summarize how to undo these operations using their

inverses

step-by-step explanation:

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.
