What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable
What is a number sentence with a variable and an equal sign called?
a variable expression
What is replacing a variable in an expression with a number value called?
Substituting.
What is the number that is multiplied by a variable in an algebraic expression?
That is often called the coefficient.
What do you call replacing a variable in an expression by a number and simplifying the result?
That is called 'solving'.

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 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

That is called 'solving'.
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.
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 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."
