x-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 ).
__n_ 2
An algebraic expression representing the sum of a number squared and 2 can be written as ( x^2 + 2 ), where ( x ) is the variable representing the number. In this expression, ( x^2 ) indicates the number squared, and adding 2 accounts for the additional term.
x+2=
1/2 n
__n_ 2
[Number of players]/2
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
