Answer:
The average value of a, b and c is [tex]\frac{2c}{3}[/tex]
Step-by-step explanation:
Average value:
Sum of all values by the number of values.
In this question:
3 values, a, b and c.
We have that:
[tex]A = \frac{a+b+c}{3}[/tex]
Since [tex]a+b = c[/tex]
[tex]A = \frac{a+b+c}{3} = \frac{c+c}{3} = \frac{2c}{3}[/tex]
The average value of a, b and c is [tex]\frac{2c}{3}[/tex]
