A variable is an unknown, so algebra equations contain them. there are lots of different ways you can see a variable though whether it be in chemistry physics , business or just a math course. They can be huge equations or just simple ones. But there will be an unknown. Usually denoted as a "x" or "y" etc
For example 4x+3y^2+10x-2y+8x
It is a constant.
4x- x
an algebraic expression
An expression.
yes.
The control does not contain a variable!:)
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
A local variable is a variable that can only be called on by the module. Where as a global variable can be called upon by any module. Only statements made inside the same module can call on a local variable.
Decision statements are statements that are used for taking logical decisions. They contain a condition whose output is a boolean true or false. Ex: if (name.equals("Rock")) { System.out.println("Hi Rocky!!!"); } The output of the if condition will depend on the value that the variable name holds. This is a decision statement
Usually, the name of the variable can be most anything. This type of variable is called a LOGICAL variable.
the variable that is most difficult to test
It is a constant.
The if and switch statements are commonly referred to as decision statements. When we use decision statements in our program, we're asking the program to evaluate a given expression to determine which course of action to take. It decides the control flow of the program.
A variable is an entity that may change its value. In a program, the result of the processing statements are stored in the computer's memory.
Part 3 did not contain that variable. The question wants you to say part 2 as that is the obvious answer, but it's a trick. Part 2 actually does contain that variable if you look hard enough.But I didn't tell you that.
All of them contain variable amount of minerals.
Terms that contain the same variable is called "like terms".
