What is the algebraic expression for 5 less than a certain number
5-w=
32 - n/2
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 ).
As an algebraic expression it is: 2x-9
To write an algebraic expression for "five less than the product of two and a number," let the variable ( x ) represent the number. The product of two and the number can be expressed as ( 2x ). Therefore, five less than this product is represented by the expression ( 2x - 5 ).
You write it as5nNothing more, nothing less.
To write "25 less than a number" as an algebraic expression, you would represent the unknown number as a variable, such as "x." Therefore, the algebraic expression would be written as "x - 25." This expression indicates that you are subtracting 25 from the unknown number represented by "x."
