There are 80 cookies at the bakery. each cookie is either chocolate chip or sugar cookie. there are 4 more chocolate chip cookies than 3 times the number of sugar cookie(s). how many sugar cookies are there?

14 sugar cookies,use 3x+4=y and substitute into the equation x+y=80 and you get 14 for x which I set up as sugar cookies

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.
