What three numbers have an average of 179?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 179. This means if we add these three numbers together and divide by 3, we should get 179.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 179 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 179 * 3 = x + y + z
- So, the sum of our three numbers should be: 537
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 537.
Solution 1:
179, 179, 179
Verification:
(179 + 179 + 179) / 3 = 537 / 3 ≈ 179
This solution is correct!
Solution 2:
179, 179, 179
Verification:
(179 + 179 + 179) / 3 = 537 / 3 ≈ 179
This solution is correct!
Solution 3:
140, 81, 316
Verification:
(140 + 81 + 316) / 3 = 537 / 3 ≈ 179
This solution is correct!
Solution 4:
358, 158, 21
Verification:
(358 + 158 + 21) / 3 = 537 / 3 ≈ 179
This solution is correct!
Solution 5:
385, 59, 93
Verification:
(385 + 59 + 93) / 3 = 537 / 3 ≈ 179
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 537 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.
