If the moving object is undergoing constant acceleration, then
(take the average of the initial and final velocities, if they're given)
If you don't know the acceleration or initial/final velocities, then you have to resort to the usual definition,
where 
is the change in position and 
is the duration of the interval.

Because we do what we don
4/3 * pi * radius^3 is the formula for volume of a sphere.
By the additive property of equality, the equations John wrote are equivalent.
<h3>Additive property of equality: Determining equivalent equations</h3>
From the question, we are to determine if the equations John wrote are equivalent.
From the given information,
John wrote that
5 + 5 = 10
Then,
He added n to both sides of the equation to get
5 + 5 + n = 10 + n
From the Additive property of equality, we have that
"<em>If we add or subtract the same number to both sides of an equation, the sides remain equal</em>."
Since, John added the same number, n, to both sides of the equation, the equations John wrote are equivalent.
