Final answer:
The algebraic expression 3V - v represents the difference between V and v.
Step-by-step explanation:
The algebraic expression 3V - v represents the difference between V and v.
To understand this, let's assume that V represents a certain value and v represents another value. If we subtract v from 3V, we are finding the difference between these two values. For example, if V = 5 and v = 2, then 3V - v = 3(5) - 2 = 15 - 2 = 13.
