When there's more than one letter, and you just have to solve for one variable, you can just solve it like you would any other equation. Treat the other variables like numbers and add, subtract, multiply, and divide them to both sides of the equation in order to isolate the variable you want to solve for.

$t= \frac{pd}{2x} \\ \\ t*2x= \frac{pd}{2x}*2x \\ \\ 2tx=pd \\ \\ \frac{2tx}{2t} = \frac{pd}{2t} \\ \\ x=\frac{pd}{2t}$

OK. Then let's just give the other letters different names.

Instead of T = p d / 2x

let's write Tiger = pig dog / 2x

Multiply each side by 2x : 2x Tiger = pig dog

Divide each side by Tiger : 2x = pig dog / Tiger

Now divide each side by 2 : x = pig dog / 2 Tiger

Of course you would not hand it in on a homework sheet like that.
You would change it back to
x = p d / 2 T .

To which set or sets does the number 12 belong? real numbers and natural numbers only real numbers, whole numbers, and integers

First off, let's take a look at what these numbers are:

Real numbers: It can be any numbers,both rational and irrational.

Natural numbers: The number has to be integer and positive.

Integers: A number without fraction or demical place.

Whole number: The number has to be natural and cannot be negative.

Therefore, as 12 is a positive number with no demical place or fraction, it is real numbers,integers, whole numbers, and natural numbers.

Hope it helps!

Real life scenarios of acute angles are:

Sighting a ball from the top of a building at an angle of 55 degrees.
The angle between two adjacent vanes of a fan that has 6 vanes

<h3>What are acute angles?</h3>

As a general rule, an acute angle, x is represented as: x < 90

This means that acute angles are less than 90 degrees.

<h3>The real life scenarios</h3>

The real life scenarios that involve acute angles are scenarios that whose measure of angle is less than 90 degrees.

Sample of the real life scenarios that satisfy the above definition are:

Sighting a ball from the top of a building at an angle of 55 degrees.
The angle between two adjacent vanes of a fan that has 6 vanes
