Can someone help and tell me what the answer is? Also no it’s not the third one because I submitted it like 10 mins ago and this was the only one I got wrong and when I checked it said it was wrong. Also I’ll mark you brainlist if you explain please and thanks!

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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.

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
