Final answer:
The calculated value of the expression '2a+b' with 'a' as 1000 and 'b' as 5 is 2005.
Step-by-step explanation:
The question asks us to calculate the expression 2a+b given that a=1000 and b=5. To solve this, we substitute the given values into the expression:
2a+b = 2(1000) + 5 = 2000 + 5 = 2005.
So, the calculated value of the expression 2a+b when a equals 1000 and b equals 5 is 2005.
