What three numbers have an average of 175?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 175. This means if we add these three numbers together and divide by 3, we should get 175.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 175 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 175 * 3 = x + y + z
- So, the sum of our three numbers should be: 525
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 525.
Solution 1:
175, 175, 175
Verification:
(175 + 175 + 175) / 3 = 525 / 3 ≈ 175
This solution is correct!
Solution 2:
175, 175, 175
Verification:
(175 + 175 + 175) / 3 = 525 / 3 ≈ 175
This solution is correct!
Solution 3:
114, 382, 29
Verification:
(114 + 382 + 29) / 3 = 525 / 3 ≈ 175
This solution is correct!
Solution 4:
70, 156, 299
Verification:
(70 + 156 + 299) / 3 = 525 / 3 ≈ 175
This solution is correct!
Solution 5:
419, 7, 99
Verification:
(419 + 7 + 99) / 3 = 525 / 3 ≈ 175
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 525 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.
