Ethan and two of his friends went to the movies. They originally had a total of $30. Each boy had the same amount of money and spent $8.25 on a ticket. How much money did each boy have left after buying his
ticket?
(c) Write an equation you could use to solve this problem. (Hint: distributive property)
Use m for your variable.

See below

Step-by-step explanation:

According to the question we can set the following equation:

3(m + 8.25) = 30

Solving for m if you need:

m + 8.25 = 30/3m + 8.25 = 10m = 10 - 8.25m = 1.75

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
