Question

What is the coefficient of $x$ in the expression $5+x?$

• A. $0$
• B. $5$
• C. $1$
• D. $-1$

Answer 1

The correct option is C $1$

$\underset{–}{\text{Coefficient of an Algebraic Expression:}}$
A coefficient is a number multiplied by a variable. For example: in expression $3p+2,$ coefficient of $p$ is $3.$

$\underset{–}{\text{Note:}}$
$\bullet$ A coefficient is always attached to a variable.
$\bullet$ A variable without any number attached to it, has a coefficient of $1.$

In the expression $5+x,$ there is an invisible $1$ attached with the variable $x.$ As depicted in below figure,
Therefore, coefficient of $x$ is $1.$

As a result, option (c.) is the correct choice.
