Jacob had 15 apples and gave 10 to his brother. If he had 21 apples and wanted to give the same percentage to his brother, how many apples should he get?

14 apples

Step-by-step explanation:

10/15 = 2/3 = 66 2/3%

21 / 3 = 7

7x2 = 14

14 apples

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.
