In order to make a the subject of this equation , we need to get a by itself .
The current equation is :
v = u + at
Subtract u on both sides :
v-u=at
Now, divide by t on both sides :
v-u/t=a

Lets say billiard balls are arranged in rows to form an equilateral triangle, then the first row consists of 1 ball, second row consists of 2 balls, and third row consists of 3 balls, and so on. So there must be balls in the
row.
So, the total number of balls that forms the equilateral triangle with rows is:
Let and
be the total number of balls in the first and second arrangements respectively.
Then,
It has been said that there were 11 lesser balls in the second arrangement:
Since,
multiplying both the sides by 2
Therefore,
So, there were 125 balls at the set.
