Answer: [tex]2.5[/tex]
Step-by-step explanation:
Given the following expression:
[tex]ab-0.5b[/tex]
And given these values of "a" and "b":
[tex]a=1\\ b =5[/tex]
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:
[tex]ab-0.5b=(1)(5)-0.5(5)[/tex]
2. Now, you need to solve the multiplications:
[tex]=5-2.5[/tex]
3. Finally, you must solve the subtraction. Then:
[tex]=2.5[/tex]
