Question

If The Value Of X Is 3 , Dx=12 then value of D Is.

Answer 1

Answer:

The value of D is 4

Step-by-step explanation:

Given that the value of X is 3 and the value of DX is 12

$= > X = 3 \\ DX = 12$

We are required to find the value of D which can be found by dividing both the left hand side and right hand side of the above two relations and thus eliminating the unwanted term X.Dividing the two relations we get,

$\frac{X}{DX} = \frac{3}{12} \\ = > \frac{1}{D} = \frac{1}{4} \\ = > D = 4$

Therefore,the value of D is found to be 4.

Answer 2

As per the data given in the above question.

We have to find the value of D.

Step-by-step explanation:

Given,

$value \: of \: x= 3$

$Equation \: is \: Dx=12$

Step-1:

We have to find the value of D and D is a variable .

Here ,

$Dx=12$

Put the value of x= 3, we get

$D \times 3=12$

STEP-2:

Variable and constant value can't be multiply to each other , so shift the 3 toward the 12 .

The 3 becomes in division of 12

$D = \frac{12}{3}$

Divide the right hand side value ,

We know that 3 times 4 means 12

$D = 4$

Hence,

The value of D is 4 with given equation Dx=12.

Proof:

Dx=12

D=4 and x= 3

4×3=12

12=12
