" 5(x+2) " is.
[Number of players]/2
2x - 2
The variable is d, in the algebraic expression 7d+2
7x + 2
An algebraic expression has 2 or more terms in it without an equality sign.
32 - n/2
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
Where the number=n: (n/2)+8.
n = number 2(n + 15) ======
An algebraic expression would be something like d / 2, or f + 3.
x/y - 4 = 2
