What is x when 89 divided by x equals 30?

To find the answer, just divide the dividend by the quotient: 89 ÷ 30 = 2.9666666666667

To prove this, let's compute 89 divided by 2.9666666666667: $\frac{89}{2.9666666666667} = 30$

How does it work?

Asking what the value of x could be when 89 divided by x gives a result of 30, is equivalent to solving the following equation:

$\frac{89}{x} = 30$

Multiply both sides by x: $\frac{89 x}{x} = 30 x$
$\frac{89 x}{x}$ is equivalent to $\frac{x}{x} \times 89$ , which simplifies to $1 \times 89$ (or just $89$ ).
Thus, the equation becomes: $89 = 30 x$
To find x, divide both sides by 30: $\frac{89}{30} = \frac{30 x}{30}$
Which gives, after simplification: $2.9666666666667 = x$ (or $x = 2.9666666666667$ )

So, if the dividend is 89 and the quotient is 30, the divisor is 2.9666666666667.
