If the number is 'z', then five less than twice the number is ( 2z - 5 ).
displaying a variable in php using echo statement? <?php $name="ram"; //declaring and defining the variable echo "$name"; //printing the variable using echo command ?>
Create a number line from zero to one where the gradations are in tenths.
You can unset a variable in PHP by setting it to NULL. You can set a variable to NULL by declaring it normally, or using the function "unset()". Both methods are acceptable, and accomplish the same thing. Examples of both: ---- $variable = NULL; ---- unset($variable); ----
Attention students, if you are failing any subject, there is after school tutoring twice a week to help you do better.
By using a third temporary variable. $tmp = $a; $a = $b; $b = $tmp;
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.
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
Circle graphs are use to illustrate the breakdown of a single variable into its components.
"Five Times the Difference" implies multiplying five by an operation of subtraction so you would represent it by using parentheses: 5(number - number). "Twice a number" means you are multiplying an unknown number, X, by 2. So you represent this as 2x. The equation now looks like: 5(2x - 14) "Is negative ten" basically means "Is Equal to -10." The final equation should look like: 5(2x - 14) = -10 Solve using distribution and combining like terms.

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.
