Write an algebraic expression for each situation or problem 1. You bought x CD’s online and y CD’s from a store how many total CDs did you buy? 2. You want to evenly divide 15 tickets between p people. How many tickets will each person receive?

47

step-by-step explanation:

idk what the heck he answer is, i’m just putting this here so i finish my account

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
