What would the variable expression be for double a number f?
2f
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.
Which is the variable expression for Seventeen decreased by a number y?
17 - y
Translate the phrase into a variable expression Five more than a number?
N + 5 With "N" being the variable.
What is 4 decreased by the quotient of a number and 7 as an algebraic expression?
The algebraic expression for "4 decreased by the quotient of a number and 7" can be represented as 4 - (x/7), where x is the variable representing the number. The expression first calculates the quotient of the number and 7 by dividing x by 7, and then subtracts that quotient from 4. This expression captures the mathematical operation described in the question.
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable
What do you call replacing a variable in an expression by a number?
A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46
What is the number that multiplies a variable?
The number that multiplies a variable in an algebraic expression is called a coefficient. It is the numerical factor that is multiplied by the variable to form a term in the expression.
What is the number that is multiplied by the variable in an algebraic expression?
It is the coefficient of the variable
What is to replace a variable with a number or anotherexpression in an expression?
The term for replacing a variable with another value or expression is "substitution."
What is find the numerical variable of an expression?
It is a poorly worded question. Any number in an expression can be a numerical variable.
What expression is the inverse operation of 3020?
3020 is a number, not an operation. A number cannot have an inverse operation.
What is a number sentence with a variable and an equal sign called?
a variable expression
What an expression that repesents the product of 84 and b?
The expression that represents the product of 84 and b is 84b. In mathematical terms, when you multiply a number by a variable, you simply write the number next to the variable without any operation symbol in between. So, 84 multiplied by b is written as 84b.
What is the meaning of expression with variable?
It means that it is an expression, and it contains one or more variables. An "expression" is anything that can be calculated to obtain a number. For example, all of the following are expressions: 5 1 + 2 a a + 1 2a a + b
What is the meaning of variable in algebraic expression?
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
