What is numerical number of a term that contains a variable?
The numerical factor of a term is called the "coefficient."
What number is the coefficient number?
the number next to a variable that multiplies the variable
What is a variable replaced by a given number?
Yes since a number and a variable and a number are a symbol.
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 a number that multiplies a variable?
A coefficient is a number that multiplies a variable.
A term such as 36 that contains no variable?
a constant is a number with no variable
What is the number of a variable that contains the exponent?
Depends on the problem.
What is a open number sentence?
An open number sentence is a sentence which contains a variable. A variable is a unknown number but replaced with a letter and can be on either side of an equals sign.
What is an open number sentence?
An open number sentence is a sentence which contains a variable. A variable is a unknown number replaced with any letter and can appear on either side of the equals sign.
What is numerical number of a term that contains a variable?
The numerical factor of a term is called the "coefficient."
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 contains the element polonium?
Polonium contain 84 protons an electrons and a variable number of neutrons, depending on the isotope.
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
A hydrogen atom which has lost an electron contains?
After it has lost an electron, a hydrogen ion contains one proton and a variable number of neutrons depending on the isotope (usually none).
A hydrogen atom which has lost an electron contains what?
After it has lost an electron, a hydrogen ion contains one proton and a variable number of neutrons depending on the isotope (usually none).
What is a variable minus a number and variable?
a variable minus a number and the same variable is b-6b= -5b
What number is the coefficient number?
the number next to a variable that multiplies the variable
