Which algebraic expression models the given word phrase 6 times the sum of a and b

6( a+ b).

Step-by-step explanation:

Given  :  phrase 6 times the sum of a and b

To find : Which algebraic expression models the given word phrase.

Solution : We have given that

phrase 6 times the sum of a and b

According to question :

Sum of a and b is a + b.

6 times of sum of a and b

Here the time mean multiplication .

6  * ( a+ b).

Therefore, 6( 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.

step-by-step explanation:

i believe the answer is c.
