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, 
Use the equation 459/x=85/100. then you cross multiply 459 and 100 to get 45900. after that you divide 45900 by 85 to get x=540
we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Combine like terms

Divide by
both sides


therefore
<u>the answer is</u>
the value of p in the linear equation is 
The solution of the equations is A) (-2,-4)
