TO DETERMINE

The value of x

EVALUATION

Here it is given that x , 6 , 8 , 12 are in proportion

Thus we have

x : 6 = 8 : 12

$\displaystyle \sf{ \implies \frac{x}{6} = \frac{8}{12} }$

$\displaystyle \sf{ \implies 12x = 48 }$

$\displaystyle \sf{ \implies x = \frac{48}{12} }$

$\displaystyle \sf{ \implies x = 4}$

Answer 2

Answer:

The value of x will be 4.

Step-by-step explanation:

In context to questions asked

We have to determine the value of x,

Given that,

$x: 6:: 8: 12$

It is written as:

=> $\frac{x}{6}=\frac{8}{12}$

By using the method of cross-multiplication,

=> 12 $\times$ $x$ = 8 $\times$ 6

Multiplying the numbers,

=> 12$x$ = 48

Divide both sides by 12,

=> x = 4

Hence, the required solution is 4.
