Question

In the expression $7x+5,$ what is the coefficient of $x?$

• A. $7$
• B. $5$
• C. $1$
• D. None of the above

Answer 1

The correct option is A $7$

$\underset{–}{\text{Coefficient of an Algebraic Expression:}}$
A coefficient is a number multiplied by a variable. e.g. 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 given expression $7x+5,$ coefficient of $x$ is $7.$

Therefore, option (a.) is the correct choice.
