Answer:
fraction of gallon is in each bottle.
Step-by-step explanation:
As per the given condition: G.O is going on a hike in the mountains on a hot summer day he has 4/5 gallon of water that he split into 4 bottles.
⇒ in 4 bottle he has
gallon of water.
Unit rates defined as when are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, then they are called unit rates.
By unit rate definition,
In 1 bottle he has =
gallon of water.
therefore, the gallon in each bottle in fraction is, 
0.25 divided by 1.075 is 0.2325..
But I think 1.075 divided by 0.25 sounds more right, in case that is the problem then the answer is 4.3
The answer would be (7<em>x</em>+2)(<em>x</em>+2)
