Mrs. cook and mrs. jones were both grading papers at a coffee shop, they then finish at home. mrs. cook graded 10 papers at the coffee shop and now grades 3 papers an hour at home. mrs jones graded 4 papers at the coffeee shop and now grades 5 papers an hour at home. in how many hours would the teachers be done grading the same amount of papers? write and solve a system of equations. show your steps

This is mainly fith grade math, but, the answer is... (drumroll) 99!! (im not completely sure my math is correct my give it a go!) Also thanks for helping me on my Social Studies! I owed you one!

Step-by-step explanation:

Just make a graph and calculate.

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

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.
