To find the average value of the two numbers, follow these steps:
1. Add the two numbers:
[tex]\[
7 + 9 = 16
\][/tex]
2. Calculate the average:
The average of two numbers is calculated by dividing their sum by 2.
[tex]\[
\text{Average} = \frac{\text{Sum of the two numbers}}{2} = \frac{16}{2}
\][/tex]
3. Simplify the division:
[tex]\[
\frac{16}{2} = 8.0
\][/tex]
So, the average value of 7 and 9 is [tex]\( 8.0 \)[/tex].
