Answer:

a. v

Explanation:

Given


3v - 8

Required

Identify the variable

Literary, variable means things that change in values;

Going by this definition, we have that:

3 -> This is not a variable because its value will always be 3

v -> This is a variable because its value can change once its value changes, the result of the expression will also change

- -> This is not a variable; it is an arithmetic operator to subtract

8 -> This is not a variable because its value will always be 8

Take for instance


v = 2


3v - 8 = 3 * 2 - 8 = 6 - 8 = -2

When
v =5


3v - 8 = 3 * 5 - 8 = 15 - 8 = 7

Notice that there's a difference in both results;

This is as a result of v being a variable
