What is numerical number of a term that contains a variable?
The numerical factor of a term is called the "coefficient."
Can you add a constant with a number with a variable?
Yes, you can add a constant to a number that contains a variable, but you cannot combine them into a single term. For example, if you have the expression (3x + 5), you can express it as the sum of (3x) (the term with the variable) and (5) (the constant). The two parts remain distinct in the expression, but they can be written together as a single expression.
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
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).
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
a number when substituded in to an open sentence makes a true statement?
An equation or an inequality that contains at least one variable is called an open sentence. ... When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.
