The inventory of single houses is 980 in the housing market last year. After some of them were sold, there are 637 single houses left. What was the percentage decrease in the number of single houses?

Step-by-step explanation:

637*100=63700

63700/980=65

so 637 is 65%

so 100-65=35

so 35%decrease

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.
