3. If a+b=c, then what is the average value of a,b are c?<br>

Vladimir [108]

Answer:

The average value of a, b and c is $\frac{2c}{3}$

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:

$A = \frac{a+b+c}{3}$

Since $a+b = c$

$A = \frac{a+b+c}{3} = \frac{c+c}{3} = \frac{2c}{3}$

The average value of a, b and c is $\frac{2c}{3}$
