Answer In 1637, a very important book was published in France by Rene Descartes. he used the letter 'x', 'y','z' to stand for the unknown amounts in his maths problems. his book became very popular. other mathematicians followed his practice & started using the letter 'x' to denote the unknown.
Algebra is the basis of maths you can use it to solve unknown terms such as x. For example: 3x - 3 = 0 3x = 3 x = 1
You have to find out what the unknown number is. Example: x= 2y-4 y=12 What this is saying is you have to find out what x is if y is 12. So the sum reads 2x12-4. X=20
If we let the unknown number be represented by the variable x, then six more than the unknown number would be x + 6. This expression represents adding six to the unknown number. So, if you have an unknown number x, adding six to it gives you x + 6.
In maths most vairables are represented with letters. EG. A+B=C So for a best guest and in this case i would say X would be the best for an unknown variable that could change, as x is normally associated with many unknowns.
X is an unknown number.
in maths it denotes as10
An unknown number.
It is usually algebra whereas x is an unknown variable.
In algebra whereas x is usually the unknown variable to be solved.
In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
In maths lower case c is a constant and denotes the speed of light
the curvy 'x' in maths stands for an unknown number. So 'x=2+3', doesn't tell us what x is, but we can work it out. (x=5 in this case)
Algebra is the basis of maths you can use it to solve unknown terms such as x. For example: 3x - 3 = 0 3x = 3 x = 1
Usually in algebra the term "unknown" is used for a variable ( commonly designated as x ) you are trying to solve for. For instance the mathematical expression 2 + x = 5 may be presented to the student as a problem. The answer is to solve for the unknown or x. The solution would be x = 3
You have to find out what the unknown number is. Example: x= 2y-4 y=12 What this is saying is you have to find out what x is if y is 12. So the sum reads 2x12-4. X=20
This depends entirely on the context, but usually, an x denotes an unknown amount in an expression, while n denotes where a term is in a sequence. Examples: I have x amount of apples. My sister has twice that amount. How many does she have? 2x A sequence goes 1,2,3,4... etc. The term "n" is a certain amount. Which term is twice that amount? 2n This is how they are usually used, but they can also be interchangeable if you want to use them interchangeably. x and n both just mean "an unknown value".
Ah ha! In algebra, a letter stands for an unknown value! Some of the most common letters used in algebra are: x, y, n, and p. Some might say 'n' is an uNknown number! haha
