You can put this solution on YOUR website! If the average (arithmetic mean) of three numbers is 6, and the sum
of the two larger numbers is 16, what is the value of the smallest number?
:
3 numbers, a, b, c, (c is the smallest)
write an equation for each statement
: = 6
multiply both sides by 3
a + b + c = 18
a + b + 0 = 16; (the 2nd statement)
------------------subtraction eliminates a and b, find c
c = 2 is the smallest number
