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 a comparison of numbers or variables that can be written as a fraction form?
They are known as ratios.
What is Value of 5x plus 9y plus 5?
The variables have no known values and as an expression it is: 5x+9y+5
What does constant mean in an algebraic expression?
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
How many algebraic terms are there in 5a 2d a 6d?
Just 2. The letters are all known as variables and the numbers are just numbers. Even though there are different numbers and letters, they all represent the same things.
Does a variable expression consist of numbers variables and operations?
Yes. A variable expression is also known as an algebraic expression. An equation consists of variable expressions on each side of an equality.
Do All expressions contain variables?
No, not all expressions contain variables. An expression is a mathematical phrase that combines numbers, variables, and mathematical operations. A variable is a symbol that represents a quantity that can vary, such as x or y. Some expressions may only contain numbers and mathematical operations, such as addition, subtraction, multiplication, and division. For example, "3 + 5" is an expression that only contains numbers and the addition operation. However, an expression that contains at least one variable is known as an algebraic expression, and this type of expression is commonly used in algebra to represent mathematical relationships between variables. For example, "2x + 4" is an algebraic expression that contains the variable x and represents a linear equation in which y is equal to two times x plus four.
What is mathematical expression of a relationship between two or more variables usually known as?
A function.
How do you evaluate an algebraic expression when I know the value of each variable?

What is a comparison of numbers or variables that can be written as a fraction form?
They are known as ratios.
What is an arrangement of numbers operations and grouping symbols known as?
It is an expression.
What are naked numbers?
Naked numbers, also known as pure numbers, are integers that are not combined with any variables or constants in an algebraic expression. They are standalone whole numbers without any additional symbols or operations attached to them. In contrast, dressed numbers are those that are part of a larger mathematical expression involving variables, coefficients, or operators. Naked numbers play a fundamental role in arithmetic and algebra as building blocks for more complex mathematical operations.
What are the numbers represented by variables called?
The numbers that are represented by a variable is better known as a coefficient. Otherwise known as a constant. The constant always stays the same such as in a scientific problem in an experiment.
Replacing each variable with a number in an expression and simplifying the result?
Substituting a numerical value for each variable in an expression and then simplifying the resulting expression is known as evaluating the expression. This process involves following the order of operations, which includes performing operations inside parentheses first, then exponents, multiplication and division from left to right, and finally addition and subtraction from left to right. By replacing variables with specific numbers, we can determine the exact value of the expression based on those inputs.
What is Value of 5x plus 9y plus 5?
The variables have no known values and as an expression it is: 5x+9y+5
What does constant mean in an algebraic expression?
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
What is The amount of increase or decrease in a function usually written as a fraction?
When writing a function, the decreasing or increasing numbers are known as variables. Before those variables are known, they are written as alphabetical letters, often "x," "y" or "z."
