Question

How to evaluate 8x for each value of x for x=0.5

Answer 1

8x will equal 4 because i multiplied both together.

Answer 2

To evaluate $8x$ at $x=0.5$, we just have to plug in $0.5$ wherever we see $x$.

After substituting $x=0.5$ for every value of $x$, we then simplify.

So, on substitution, we have

$8x=8(0.5)$

Change the $0.5$ to $\frac{1}{2}$ to help you multiply easily.

$\Rightarrow 8x=8\times \frac{1}{2}$

Simplify to obtain,

$8x=4$
