Brianna made 3 34 cups of granola. She gave 1 12 cups of the granola to her mom and 23 of a cup to her sister. How much granola did she have left?

Brianna left with 199 cups of granola.

Step-by-step explanation:

Total cups of granola = 334

granola given to mom = 112

granola given to sister = 23

the number of cups of granola she left is

= 334 - 112 - 23

= 199

So, Brianna left with 199 cups of granola.

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.
