Solution:
Let's denote the three consecutive odd integers as x, x + 2, and x + 4
x + (x + 2) + (x + 4) = x + 40
⇒ 3x + 6 = x + 40
⇒ 2x + 6 = 40
⇒ 2x = 34
∴ x = 17
The three consecutive odd integers are 17, 19, and 21
∴ The middle number is 19
Solution:
To find the smallest value of the expression 2x - y, we need to analyze the possible values for x and y within their respective ranges.
Given:
- 3 ≤ x ≤ 5
- 5 ≤ y ≤ 3
We want to minimize the expression:
2x - y
Step 1: Determine the minimum value of 2x
The minimum value of x is - 3
Therefore, the minimum value of 2x is: 2(- 3) = - 6
Step 2: Determine the maximum value of y
The maximum value of y is 3
Step 3: Calculate the smallest value of 2x - y
The smallest value of 2x - y occurs when 2x is minimized and y is maximized:
2(- 3) - 3 = - 6 - 3 = - 9
∴ The smallest value of 2x - y is - 9
