The mathematical expression for "nine less than a certain number" can be represented as ( x - 9 ), where ( x ) is the certain number. This expression indicates that you subtract 9 from that number.
x4 - 3
x + 8 < 144
To express "40 less than a number," you can use a variable to represent the number, such as ( x ). The mathematical expression for this would be ( x - 40 ), indicating that you subtract 40 from the value of ( x ). This expression effectively captures the concept of reducing the number by 40.
To express "two less than five times a number," we can use a variable, say ( x ), to represent the number. The phrase translates to the mathematical expression ( 5x - 2 ). This indicates that you first multiply the number by five and then subtract two from the result.
If there is an equal sign, it is called an equation; if there is a less-than, a less-than-or-equal, a greater-than, or a greater-than-or-equal sign, an inequality; if there is none of these, an expression.

If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
The number expression for "18 less than 25" can be written as ( 25 - 18 ). This simplifies to ( 7 ). Thus, the expression represents the value ( 7 ).
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.
To write the algebraic expression for "2 less than a number," first define the number as a variable, commonly ( x ). The phrase "2 less than" indicates subtraction, so the expression would be ( x - 2 ). Therefore, the algebraic expression is ( x - 2 ).
The expression that shows 22 less than triple a number can be written as (3x - 22), where (x) represents the number. Here, "triple a number" is represented by (3x), and subtracting 22 gives the final expression.
