Question

The midpoint between $x$ and $40$ is $25$.

Find $x$.

Answer 1

Step-1: Midpoint between two numbers.

Let $a$ and $b$ are the two numbers.

So, the midpoint between $a$ and $b$ is $\frac{a+b}{2}$.

Step-2: Find the value of $x$.

Given,

The midpoint between $x$and $40$ is $25$.

By Formula the midpoint between $x$and $40$ is $\frac{x+40}{2}$

So, value of $x$ is calculated as follow:

$\begin{array}{rcl}\frac{x+40}{2}& =& 25\\ x+40& =& 50\\ x& =& 10\end{array}$

Hence, the value of $x$ is $10$.
