Final answer:
The value of the expression (a - 1) + 22 / (2a) when a = 2 is calculated by performing the operations step-by-step, resulting in the value 6.5.
Step-by-step explanation:
To solve the expression (a - 1) + 22 / (2a) when a = 2, we plug in the value of a:
⅓ = (2 - 1) + 22 / (2×2)
The calculation simplifies as follows:
- First, calculate inside the parenthesis: (2 - 1) = 1
- Then, calculate the denominator of the fraction: (2×2) = 4
- Next, divide 22 by 4 to get the quotient: 22 / 4 = 5.5
- Now, add the two results together: 1 + 5.5 = 6.5
However, there seems to be a typo or irrelevant part of the question as the symbol α (alpha) and the value b are mentioned but are not used in the calculation. With the given values, the result of (a - 1) + 22 / (2a) when a = 2 is 6.5.
