If the average(arithmetic mean) of 5 and r is 7 and the average of 3 and s is 3 , what is the average of r and s?

Norma-Jean [14]

Answer:

C

Step-by-step explanation:

Calculate the values of both r and s, that is

$\frac{5+r}{2}$ = 7 ( multiply both sides by 2 )

5 + r = 14 ( subtract 5 from both sides )

r = 9

and

$\frac{3+s}{2}$ = 3 ( multiply both sides by 2 )

3 + s = 6 ( subtract 3 from both sides )

s = 3

Hence

$\frac{9+3}{2}$ = $\frac{12}{2}$ = 6 → C
