Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
Your variable (a number) X, minus 100. X - 100
The expression can be thus: 3x-3 whereas x is the unknown variable
In this case, you'll have to use a variable. Variables are basically a symbol which stands for a number. Let's use the variable "m". You're searching for 58 less than a number. That is basically just "word form" for a number, or a variable, minus 58. So if we use the variable "m", the expression will be m-58. Remember that you can use any variable you want.
It is: p-2
Yes, an expression can have more than one variable.
7 less than a number is an algebraic expression. Given the number the expression can be evaluated. 7 is less than a number is a statement in the form of an inequality. It is true for some values of the number and not for others.
z - 7
5 less than y
7 less than k
N + 5 With "N" being the variable.
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
(x + 9)
s + 9
n + 11
It is x/3 - 8
a - 4
It means that the number or expression on the left of the symbol is less that the value or expression to the right, or that they are equal.
( n - 16 )
The expression is: 2x-16
The expression is n - 3.
d - 2.5
A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.
