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
How do you write an expression that represents the sum of a number and 12?
To write an expression that represents the sum of a number and 12, you can use a variable to represent the unknown number. For example, if you let the variable ( x ) represent the number, the expression would be ( x + 12 ). This indicates that you are adding 12 to whatever value ( x ) holds.
What do I replace a variable with a number?
To replace a variable with a number, simply identify the variable in your equation or expression and substitute it with the desired numerical value. For example, if you have the expression ( x + 5 ) and you want to replace ( x ) with 3, you would write it as ( 3 + 5 ). This substitution allows you to evaluate the expression or solve an equation more easily.
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).
How do you write the quotient of a number and 6 into an expression?
To write the quotient of a number and 6 as an expression, you can represent the number as a variable, such as ( x ). The expression would then be written as ( \frac{x}{6} ). This indicates that the number ( x ) is being divided by 6.
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 coefficient of X in the expression 2x + 10y?
2 would be the coeeficient the coefficient is the number before the 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 is the coefficent in this algebraic expression 7d plus 2?
The coefficient would be the number multiplied by the variable, in this case: 7
