How do you evaluate an algebraic expression?
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
What is a variable expression that has a decreasing value as the value of the variable increases?
what is a variable expression that has a decreasing value as the value of thevariable increases?
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 the algebraic expression for p multiplied by 3?
The algebraic expression for p multiplied by 3 is 3p. This is written as the coefficient (3) multiplied by the variable (p). In algebra, when a number is placed next to a variable without an explicit multiplication sign, it is understood to be multiplication. Therefore, 3p represents three times the value of p.

Write an algebraic expression with the variable X that has a value of three when evaluated?
An algebraic expression that has a value of three when evaluated could be ( X + 2 ). If we set ( X + 2 = 3 ), then solving for ( X ) gives us ( X = 1 ). Therefore, the expression ( X + 2 ) evaluates to 3 when ( X ) is 1.
How can you have different values in algebraic expressions?
When the value of a variable in an algebraic expression changes, the value of the expression can change.

How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
How do you evaluate an algebraic expression when I know the value of each variable?
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
What is to find the value of a numerical or algebraic expression?
to solve for the variable
How do you find a specific numerical value for an algebraic expression?
you have to deduce the variable and evaluate the expression.

How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.
What is an expression in algebra terms?
In algebra, an expression is a combination of numbers, variables, and mathematical operators (such as addition, subtraction, multiplication, and division) that represents a value. Unlike an equation, an expression does not include an equality sign and cannot be solved for a specific value. For example, (3x + 5) is an algebraic expression where (x) is a variable. Expressions can be simplified or evaluated by substituting values for the variables.
The number that is in front of the variable in an algebraic expression?
The number in front of the variable in an algebraic expression is called the coefficient. It indicates how many times the variable is being multiplied. For example, in the expression (3x), the coefficient is 3, meaning (x) is multiplied by 3. Coefficients can be positive, negative, or even fractions, affecting the overall value of the expression.
