8a - 10.5b

subtitute the values of a = 1/4 and b = 10 to the expression:

8 · 1/4 - 10.5 · 10 = 2 - 105 = -103

Answer:

[tex]8a-1+0.5b=6[/tex] when [tex]a=\frac{1}{4}[/tex] and b=10.          

Step-by-step explanation:

Given : Expression [tex]8a-1+0.5b[/tex] when [tex]a=\frac{1}{4}[/tex] and b=10.

To find : Solve the expression?

Solution :

Step 1 - Write the expression,

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

Step 2 - Substitute [tex]a=\frac{1}{4}[/tex] and b=10

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

Step 3 - Solve,

[tex]8a-1+0.5b=2-1+5[/tex]

[tex]8a-1+0.5b=6[/tex]

Therefore, [tex]8a-1+0.5b=6[/tex] when [tex]a=\frac{1}{4}[/tex] and b=10.
