Additive inverse; you can't just take -4.4 and make it positive.

Option (1)

Step-by-step explanation:

-8.3+9.2-4.4+3.7 john has used his first step as -8.3+9.2+4.4+3.7.

He has use additive inverse as their is no information is given about the additive inverse -4.4 can not be converted +4.4 .this is his incorrect step.

So, the correct steps are

-8.3+9.2-4.4+3.7

= (-8.3-4.4)+(9.2+3.7)

= -12.7+12.9

= 0.2

Hence, there is need to change the step  !.

Hence, the correct answer is 1.

b is the answer that makes most sense

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.
