What three numbers have an average of 579?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 579. This means if we add these three numbers together and divide by 3, we should get 579.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 579 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 579 * 3 = x + y + z
- So, the sum of our three numbers should be: 1737
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1737.
Solution 1:
579, 579, 579
Verification:
(579 + 579 + 579) / 3 = 1737 / 3 ≈ 579
This solution is correct!
Solution 2:
579, 579, 579
Verification:
(579 + 579 + 579) / 3 = 1737 / 3 ≈ 579
This solution is correct!
Solution 3:
85, 1432, 220
Verification:
(85 + 1432 + 220) / 3 = 1737 / 3 ≈ 579
This solution is correct!
Solution 4:
1421, 290, 26
Verification:
(1421 + 290 + 26) / 3 = 1737 / 3 ≈ 579
This solution is correct!
Solution 5:
1476, 124, 137
Verification:
(1476 + 124 + 137) / 3 = 1737 / 3 ≈ 579
This solution is correct!
Explanation:
As you can see, there are many possible solutions. We can find more by:
- Choosing any two numbers
- Subtracting their sum from 1737 to get the third number
Remember:
- The numbers don't have to be whole numbers.
- They can even be negative (although that might not make sense in some real-world contexts).
- The order of the numbers doesn't matter for the average.
