Question

Evaluate ab-0.5b when a=1 and b =5

Answer 1

Answer:
`2.5`

Explanation:

Given the following expression:

`ab-0.5b`

And given these values of "a" and "b":

`a=1\\ b =5`

You need to follow these steps in order to evaluate it:

1. You must substitute the values of "a" and "b" into the expression provided:

`ab-0.5b=(1)(5)-0.5(5)`

2. Now, you need to solve the multiplications:

`=5-2.5`

3. Finally, you must solve the subtraction. Then:

`=2.5`
