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 is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
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
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 is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
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 4d a variable or is it a numerical exspression?
In the context of algebra, "4d" would typically be considered a numerical expression rather than a variable. A variable is typically a letter or symbol that represents an unknown quantity that can vary, while a numerical expression is a combination of numbers and mathematical operations. In this case, "4d" represents the product of the number 4 and the variable "d," making it a numerical expression.
