"x" is a lot simpler than "the number which I don't know but am trying to calculate"
Yes and it is z=x+iy
A number is cubed if it is multiplied by itself three times. e.g. x^3 = x*x*x
The number plus sevenIf the "number" is X, then seven more than X is X+7
A line on top of a number typically indicates a repeating decimal in mathematics. For example, (0.\overline{3}) means that the digit 3 repeats indefinitely, representing the value (0.333...). In other contexts, such as in statistics, it can denote a mean or average value, often referred to as "x-bar." The specific meaning can vary based on the context in which it is used.
X represents the number '10'
Yes and it is z=x+iy
v denote sinhala and x denote tamil
Denotes - you denote/ denote/ it means
The mean is typically represented by the symbol ( \mu ) (mu) when referring to the population mean, and by ( \bar{x} ) (x-bar) when referring to the sample mean. These symbols are widely used in statistics to denote the average value of a set of data points.
An asterisk, not to be confused with Asterix who is a cartoon character, is used to denote multiplication (or times) ie a*b = a times b. Some old programming languages/computers used double asterisks to denote exponentiation ie a**b = ab. This was because x was often used to denote a variable and its use to denote multiplication could cause confusion.
400 X 400 would normally denote 400 millimeters by 400 millimeters, length and breadth of the wall mount.
If one-third of a number is 9, we can set up an equation to find the number. Let's denote the number as x. The equation would be (1/3)x = 9. To solve for x, we multiply both sides by 3 to get x = 27. Therefore, the number is 27.
Let's denote the number as x. The statement "double a number is 3 more than a number" can be mathematically represented as 2x = x + 3. By solving this equation, we find that x = 3. Therefore, the number in question is 3.
x + 4
A number is cubed if it is multiplied by itself three times. e.g. x^3 = x*x*x
The number plus sevenIf the "number" is X, then seven more than X is X+7
It can be though it is more often used to denote a variable.
