The awnser is -3.84, I did something like this problem (or exactly like it) And I just remembered the answer.
Answer:
18.75 gallons of ice
Step-by-step explanation:
I divided the 2.5 gallons of ice by the number of buckets (4) it filled to determine how many gallons of ice are in each bucket.
2.5 / 4 = 0.625
I then multiplied the amount of ice it takes to fill a bucket (0.625) by 30 buckets to get 18.75 gallons of ice.
4/7=28/(x+18)
4/7 =28/x+18
-18 | -18

__________
-17 2/7=28/x
*28 | *28

__________
-484 = x
