Question

9:x::x:16 find value of x

Answer 1

Hey buddy,
=> 9 : x :: x :16
Can be simply written as,
=> 9/x = x/16
=> x^2 = 16 x 9 = 144
=> x = (144)^1/2 = 12
=> x = 12
HOPE THIS HELPS (^o^)

Answer 2

Given,

9:x::x:16

To find,

The value of x.

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have the following:

9:x::x:16

So, we have:

$\frac{9}{x} = \frac{x}{16}$

Now, to find the value of x, we will use the cross multiplication method.

(x×x) = (16×9)

x² = 144

x = √144

x = 12

(Note that when we square root a number then the value obtained is both positive and negative. But in this case, all the numbers are positive so we have taken the positive value.)

Hence, the value of x is 12.
