Three orders are placed at a pizza shop. Two small pizzas, a liter of soda, and a salad cost $14;
one small pizza, a liter of soda, and three salads cost $15; and three small pizzas, a liter of
soda, and two salads cost $22. How much does each item cost?!

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer: your answer is a

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n

what is the question?
