Answer: [tex]6[/tex]

Step-by-step explanation:

Given the following expression:

[tex]8a-1+0.5b[/tex]

You need to substitute the given values of "a" and "b" into the expression. Notice that these values are:

[tex]a=\frac{1}{4}\\\\b=10[/tex]

Then;

 [tex]8a-1+0.5b=8(\frac{1}{4})-1+0.5(10)[/tex]

Now you must solve the multiplications:

[tex]=\frac{8}{4}-1+5=2-1+5[/tex]

The final step is to add the numbers. Therefore, you get the following answer:

[tex]=6[/tex]
