Transcript The sum, product, and average (arithmetic mean) of three integers are equal.

The sum, product, and average (arithmetic mean) of three integers are equal. If
two of the integers are 0 and –5, the third integer is
a) -5
Difficulty:
Medium
b) 0
c) 2
d) 5
e) 10
HINT
If numbers are multiplied and one of the numbers is 0, then the product is also
0. Since the sum, product, and average of the three integers are all equal, the
sum and average are also 0.
D: 5
EXPLANATION:
You have three integers, 0, –5, and x, whose sum, product, and average are equal.
Since 0 is one of the numbers, the product is 0. So the sum and average are also
equal to 0. Therefore, –5 + x + 0 = 0, and x = 5.
