Question

What is the value of this expression.

Answer 1

D.
`(27)/(4)\\\\`

Explanation:

`\mathrm{With\;x=(1)/(8)\;and\;y = (3)/(16)\;we\;get}\\\\`

`2\left((1)/(8)+4\right)-\left((3)/(16)\cdot 8\right)\\\\`

`\mathrm{Calculate\:within\:parentheses}\:\left((1)/(8)+4\right) = (1)/(8)+(32)/(8)} = (33)/(8)\\\\`

`2\left((1)/(8)+4\right) = 2\cdot (33)/(8) = (33)/(4)`

`y \cdot 8 = (3)/(16) \cdot 8} = (3)/(2)\\\\`

So

`2(x + 4) - y\cdot 8 = (33)/(4) - (3)/(2)\\\\\\= (33-6)/(4)\\\\= (27)/(4)\\\\`
