Question

How do you evaluate `(5wx)/z` if w=6, x=0.4, y=1/2, z=-3?

Answer 1

See a solution process below:

Explanation:

To evaluate this expression substitute:

`color(red)(6)` for `color(red)(w)`

`color(blue)(0.4)` for `color(blue)(x)`

`color(green)(-3)` for `color(green)(z)`

`y` is extraneous and not needed for this problem.

Substituting and calculating gives:

`(5color(red)(w)color(blue)(x))/color(green)(z)` becomes:

`(5 xx color(red)(6) xx color(blue)(0.4))/color(green)(-3) => (30 xx color(blue)(0.4))/color(green)(-3) => 12/color(green)(-3) => -4`
