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.
If it was physics or math try to solve all problems you have and try to search for more questions to solve the more you solve the more you will gain marks ,if it was a subject that needs to memorize write down the things you forget on nots and read them in the morning .. do not forget to take a break whenever you lose your passion just believe in yourself you can do it
If this is asking how to write this as a complex fraction, here's how:
First, do the whole number (4) multiplied by the diameter (4) to get 16. Then you take 16 and add this to the numerator (1) to get 17. Then your final answer is this number (17) over the original denominator (4), or 17/4
Hope this helps :)

Plug in -1 for x
and you'll get this:

Solve it further and you'll get:

Therefore,

where x = -1
