Which of the activities below are examples of projectile motion? check all that apply. a. a football thrown down the field b. a tennis ball tossed up before a serve c. an apple falling from a tree d. an airplane landing

I would state A and B are projectile motion because they are all launched at an angle and are in free fall after being launched.

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18
