How do you write a number decreased by 16 in algebraic expression?
If x is the unknown variable then it can be: x-16
Which of the following verbal expression represents the algebraic expression 2x-8?
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
What the expression for a number decreased by 19?
Let the number be x and so the expression is: x-19
What is the number that is multiplied by the variable in an algebraic expression?
It is 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
Which is the variable expression for Seventeen decreased by a number y?
17 - y
How do you write a number decreased by 16 in algebraic expression?
If x is the unknown variable then it can be: x-16
How do i Write a variable expression for the word phrase the product of 3 and a number n decreased by 7?
3n-7
How do you Write as an algebraic expression A number decreased by 25 and multiplied by 4 using x as the variable?
(x - 25)*4
What is the algebraic expression for negative fifteen is divided by a number?
-15 ----- n (-15 over a variable)
Which of the following verbal expression represents the algebraic expression 2x-8?
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
What is an expression that contains a variable a number and at least one operation?
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable
What the expression for a number decreased by 19?
Let the number be x and so the expression is: x-19
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
Explain how to translate the phrase into an algebraic expression. a number squared decreased by ten?
Sample Response: Replace keywords with variables, numbers, and operations. “A number squared” is a power where the base is the variable and the exponent is 2. “Decreased by ten” means you must subtract 10 from the squared number.
