It’s B because 2 quarts equal 0.5 gallons
It would take the bullet 25 seconds to travel 5,000 meters (:
A unit rate will always end up having one as its denominator so divide 305 by 5 which is 61 rotations/1 minute.
Consider the equation:

Subtracting '4' from both the sides of the equation, we get as


Squaring on both the sides of the equation, we get


Subtracting '2' from both the sides of the equation, we get

x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.
They are parallel. the second one is just translated up by 5.
