Question

8a-1 0.5b when a = 1/4 and b= 10

Answer 1

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 2

`8a-1+0.5b=6` when
`a=(1)/(4)` and b=10.

Explanation:

Given : Expression
`8a-1+0.5b` when
`a=(1)/(4)` and b=10.

To find : Solve the expression?

Solution :

Step 1 - Write the expression,

`8a-1+0.5b`

Step 2 - Substitute
`a=(1)/(4)` and b=10

`8a-1+0.5b=8((1)/(4))-1+0.5(10)`

Step 3 - Solve,

`8a-1+0.5b=2-1+5`

`8a-1+0.5b=6`

Therefore,
`8a-1+0.5b=6` when
`a=(1)/(4)` and b=10.
