Two points are plotted on a number line: -11.2 and 3.3. What is the distance between these two points?

Adepartment store purchases screen-printed t-shirts at a cost of $5 per shirt. they mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9

Simplify the expression. -2/5(10+15m-20n)
