Rona mixes 2 pounds of meat with some chopped vegetables to make a mixture. she divides the mixture into 4 equal portions. each portion weighs 3 pounds. which equation and solution shows the total amount of chopped vegetables she used in the mixture?

Well if each portion is 3 pounds and there is 4 portions all together it would be 12 pounds. you already know know that the meat is 2 pounds so you subtract 2 from the whole and you are left with 10. The chopped vegetables are 10 pounds in total.
The answer is
4x3=12-2=10
