Does a variable expression consists only of numbers?
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
How would you write the product of a number z and 4 as a variable expression?
4xz=16
What is an expression for 20 times a number?
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
Half the difference of 20 and a number in algebraic expression?
You have to assign some variable name to "a number", for example, "n". The difference would be: 20 - n Half this difference is: (1/2) (20 - n) Or alternately: (20 - n) / 2
How do you write an algebraic expression in words for 3x-8?
11
What would a variable expression be for twice a number?
If the number is represented by variable x, then twice the number is represented by 2x.
Does a variable expression consists only of numbers?
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
What does the variable represent in an addition or subtraction expression?
it is the number you would use to solve the problem
Is a variable a variable expression?
Yes. A variable by itself, or anything that contains a variable, would be a variable expression (unless the variable cancels out, as in "x - x", which always has the same value).
What is the coefficient of X in the expression 2x + 10y?
2 would be the coeeficient the coefficient is the number before the variable
How would 6 divided by a number be written in an algebraic expression?
It would be: 6/x whereas x is the unknown variable
What is the algebraic expression for the product of 14 times a number?
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.
What does varable expression mean?
A variable expression is an expression which contains variables(symbol that represents a certain value). For example, 4a-90. 4a-90 would be the expression an a is a variable
How would you write the product of a number z and 4 as a variable expression?
4xz=16
What is the coefficent in this algebraic expression 7d plus 2?
The coefficient would be the number multiplied by the variable, in this case: 7
Is x squared considered a variable?
In mathematics, a variable is a symbol that represents a quantity that can vary or change. In the expression x^2 (read as "x squared"), x is the variable and the exponent 2 indicates that x is being multiplied by itself. Therefore, x^2 is considered a variable term because it represents a quantity that can change based on the value assigned to x.
Why do you think a variable in an expression is called a variable?
Because it varies, otherwise it would be a constant.
