Question

Every variable has a coefficient. That’s the number it is multiplied by. According to mathematical convention, coefficients always go in front of their variable. If there is no number in front of a variable in an expression, the coefficient is 1 since the product of any number and 1 is that number. In expressions, operations can be applied directly to a variable. Here are some examples: What is the coefficient of the variable in the expression ½ + v - 3?

Answer 1

Answer:

1

Step-by-step explanation:

Answer:

There is only 1 variable and it is v.

There is no coefficient.

That means the coefficient is 1.  

Answer 2

The coefficient of the variable in the expression ½ + v - 3 is $\frac{1}{2}$

What is the coefficient

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression (including variables such as a, b, and c). When the coefficients are themselves variables, they may also be called parameters.

Given that,

$\frac{1}{2}$ is the coefficient

$v$ is the variable

$3$ is the constant

Therefore, The coefficient of the variable in the expression ½ + v - 3 is $\frac{1}{2}$
