Ababy weighed 7.25 lb at birth. at the end of 8 months , the baby weighed 2 1/2 times the birth weight. how many pounds did the baby weighed at the end of 8 months?

I've got 14 1/8

Step-by-step explanation: First I changed the decimals to fractions .

Next I multiplied the fractions , 1/4 × 1/2 = 1/8

Then I multiplied the whole numbers , 7 × 2 = 14

Last I added the products , my sum is 14 1/8

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.
