What is 1/4=1/12+1/z

Delicious77 [7]

Answer:

$\boxed {z = 6}$

Step-by-step explanation:

Solve for the value of $z$ :

$\frac{1}{4} = \frac{1}{12} + \frac{1}{z}$

-The variable $z$ cannot equal to $0$ since division by zero is undefined. SO, you multiply both sides by $12z$ , which is the least common multiple of $4$ , $12$ , and $z$ :

$3z = 12z \times (\frac{1}{12}) + 12$

$3z = z + 12$

-Take $-z$ and subtract it from $3z$ :

$3z - z = z - z + 12$

$2z = 12$

-Divide both sides by $2$ :

$\frac{2z}{2} = \frac{12}{2}$

$\boxed {z = 6}$

So, the value of $z$ of $6$ .

In the equation y=x/6, what is the value of the constant coefficient 'k?'

zhuklara [117]

Any relation is x and y is said to be a Direct variation if one is a constant multiplier of the other .In other words we can say : when one variable changes the other changes in proportion to the first.

The Direct variation equation are of the type y=k.x

Here k is known as constant of proportionality .It has a fixed value.

The given equation is y= $\frac{k}{6}$

If we compare this equation with y=k.x

Then k= $\frac{1}{6}$
