Why and how are variables used in math?
They are used in place of an unknown number or value.
Is the square root of a variable an irrational number?
That will depend on the value of the unknown variable
Is C a prime or composite or square number?
The answer depends on the value of C, which is unknown.
What if the number is unknown to find square root square root?
It is no tpossible to find the square root of an unknown number. You can, however, represent it as x0.5 or √x so that the value of the square root can be evaluated when the value of x is known.
Which equation has the same unknown value as 430 5?
"430 5" is not an equation and it does not have an unknown value. So there can be no equation which has the same unknown value.
What is four more than twice an unknown number?
You have to know the value of the unknown number to give the correct answer.

What is the absolute value of the sum of -7 and twice a number is 23 Find the number?
If you mean... -7+x*2=23 then x = 15. Done without the aid of a calculator ! The value of 'x' (the unknown number) MUST equal 30, because 30-7=23 - SO, half the unknown number must be 15!
What the vaule of x?
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
What is an answer for one-fourth of a number is the same as the square of-3?
Note : A negative number when squared becomes a positive number so, (-3)2 = 9. Let the unknown number be 'a'. Then, ¼a = (-3)2 = 9 and so, a = 9 x 4 = 36...........which is the value of the 'unknown' number.
What is the sum of an unknown number and three times the unknown number?
Four times the unknown number. Let's say the unknown number is x. x + 3x = 4x
Is it true that any value that is unknown or change is a variable?
No. A value that is unknown may not be a variable but simply a constant whose value needs to be calculated.
Multiply 45 with this number and you get 4950what is the number?
Let the unknown number be x: 45x = 4950 Divide both sides of the equation to find the value of x: x = 110
