8 + x
choosing a variable to represent one of the unspecified numbers in a problem and using it to write expressions for the other unspecified numbers in the problem.
2n/5 or (2/5)*n
The are used to represent numbers using powers of ten.
Variable means subject to change, able to vary or differ. Example : "In summer, the mountain weather was always variable." In algebra, a variable is a symbol, usually a letter, that represents one or more unknown or changing number. Example : "The variable is found using the proper equation."
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
choosing a variable to represent one of the unspecified numbers in a problem and using it to write expressions for the other unspecified numbers in the problem.
Circle graphs are use to illustrate the breakdown of a single variable into its components.
2n/5 or (2/5)*n
A single statement, using variables, can convey the same information as many, sometimes infinitely many, statements.
To swap two numbers N1 and N2, using a third variable T... T = N1; N1 = N2; N2 = T;
The standard variable is a representation of a number. Variables are typically letters that can be distinguished from numbers. The most common examples of a variable is x, y, or z. Variables that you should stay away from using are t (because it looks like an addition sign), and o (because it looks like a zero).Ex: 5x+5=15* * * * *Variables can be used to represent simultaneously mathematical procedures for a number of different values.So, for example, 5x+5 stands for "multiply your variable by 5 and add 5". For each value of the variable x, this will give a different result, but the advantage of using this notation is that you can process all of them together instead of individually.
Depending on the language you are using the default of an instance variable can be '0', 0, null, empty, '', or have a random number.
When a firm attains minimum average variable cost, the number of units of labor it is using depends on the average product.
You put that number with a little number over it depending on how many times that number is multiplied by itself.
First of all total cost of product is identified and after that using high and low method variable and fixed costs are segregated
slope can be represented by any variables, such that, the variable representing the slope is defined. by convention, mathematicians and mathematics books authors used and are using "m" as the variable for slope. (recommended to have further historical research on this matter)
