C.tons
544000 ounces converts to 17 tons.
Number 2 is 7 9/8 but its an improper fraction so you'll have to reduce that since im having trouble doing that.
Number 5 is 9 11/12
Hope this helps!
X = 5y + 30/4 - 3 is the answer.
5 because this is equivalent to 9-4 which is 5 meters, this is because he is going up 9 and then goes down 4, do 9-4, which is 5
6 / 1/3 = 18
Hope I helped!
