A symbol usually a letter used to represent a number in mathematical expressions or sentences?
X and y
What is the definition of equivalent numerical expressions?
That means that the two expressions represent the same number.
What is the letter that represent the composite number?
The letter that represent the composite number is letter C.
What is algebraic strategy for solving a system of equations when two expressions are the same?
An expression is the algebraic representation of a number - an expression has a numeric value.An equation is an algebraic statement claiming that two expressions have the same numeric value. The equation has a Boolean value (true or false).If two equations can be expressed in an identical manner (the same expression on both sides) - then these equations are the same equation.In order for a system of equations to have a solution, the number of different equations in the system must be equal to the number of variables in the system. If there are more distinct equations than there are variables, than the system has no solution. If there are less, then the system may have no solution, or infinitely many solutions.In the case described there is most likely an infinite number of solutions
Why do you use letters in algebraic expressions?
the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.
What is a variable in expressions and equations?
It represents a number that is unknown in a problem. For example,16 + x = 44.In this case "x" would represent the number 28 in the problem.

What is the definition of equivalent numerical expressions?
That means that the two expressions represent the same number.
Is there a number that can be negative or positive?
No single number can be negative or positive. There are equations or expressions whose value can be either but not a number.
How are number patterns expressions and equations used to solve problems?
the sum of a number and 16 is equal tu 45
What does the letter n represent in maths?
In math, the letter "n" is commonly used as a variable to represent a number that is not specified. It is often used in equations and formulas to indicate a variable quantity that can take on different values.
What is the letter that represent the composite number?
The letter that represent the composite number is letter C.
What does numerically equal mean?
It means that two expressions represent the same number.
Explain why x does not necessarily represent a positive number?
x may not always represent a positive number because there are equations that make a variable a negative number
What do the letters mean in algebraic equations?
The letters in most algebraic equations mostly represent the value of the number or often at times the gradient.
Letter used to represent a number?
A letter used to represent a number is a variable of sometimes a constant.
What are math statements that contains variables?
math statements that contain variables are expressions or equations that have a letter or symbol that represents a number or value. for example, if (2+N=7), N is the variable and N=5 hope this helps
