of sunscreen

Step-by-step explanation:

we know that

Yoku uses 2 ml of sunscreen to cover 50 cm² of his skin

so

Using proportion

Find out how many milliliters of sunscreen he needs to cover 325 cm² of his skin

Let

x -------> milliliters of sunscreen needed

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.
