Use one of the division strategies to solve this equation. 92 ÷ 5 = ?
A. 21 r. 4
B. 15 r. 7
C. 19 r. 5
D. 18 r. 2

There's many strategies, but the easiest one in my opinion is relating back to multiplication.

So 5 x _ = 92??

obviously nothing can since it doesnt end in a 0 or 5, but we can find the closest thing. This would be 18 (ie, 18 x 5 = 90.)

-Next, we can subtract 92 by the product and that will be the remainder.
92 - 90 = 2.

-Therefore, the answer is 18 r.2 or D.

answer: check all that apply, where the options?

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.
