Parts of an Equation
What is a letter called in an equation?
What is the first order of operation that we look for?
Parenthesis or Distributive Property
two values being compared by less than or greater than symbols
What is a variable?
Letter that represents an unknown, or what we are trying to figure out.
What do we look for in a word problem?
Evidence. Words and numbers to help form an equation.
What are the regular integers (numbers) called in an equation?
Constant(s)
What is the second step to solve an equation?
Divide by the coefficient
What does this sign mean? >
Greater than
What is a solution set?
Group of possible numbers that make an equation or inequality true
What does "to spend" mean we need to do?
Subtract
What is the integer (number) in front of the variable called?
Coefficient
What is the coefficient? 15 - 3x = 42
What are the four inequality signs?

What are the constant(s) in this equation?
4x + 15 - 2 > 18
15, -2, 18
How do we get the variable by itself on one side? (first step to solving equations)
Add or subtract constant to the other side
What kind of dot (open or solid) do we use for an inequality without an equals symbol?
Open
What does the word "per" mean to do in math?

Why can't we have negative numbers in a solution set when we are buying something?
We cannot buy a negative amount of something.
What is/are the coefficient(s) in this equation?
10x + 2(2.5) = 15x
10, 15
How do we separate the variable from the coefficient to solve an equation?
Divide (in most cases), sometimes multiple (if a fraction)

IF the coefficient is divided by a negative number
What does "reverse" mean in an inequality?
Flip the sign
How would we find out what 30% off of $20.00 items is?
Multiply 0.30 * 20 = 6
30% off of $20 is $6.00
