The ratio of girls to boys is ms. Harrington's class is 5:7. If there are 60 students in all of her classes then how many are girls?

25

Step-by-step explanation: Because if you add 5+7=12 60/12=5 5*5=25 so thats your awnser

the square root of what number? if you add that, then someone will probably answer the question.

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.
