1. In algebra, what does the term 'variable' represent?

   A fixed number that does not change A symbol that can represent a value that may change or vary The answer to an equation A mathematical operation like addition or subtraction

   ✓ A symbol that can represent a value that may change or vary

   A variable is a symbol, usually a letter, that stands for a quantity that can change or take on different values.

2. What is an 'expression' in algebra?

   An equation that states two expressions are equal A statement that is always true A combination of numbers, variables, and operations A single number without any variables

   ✓ A combination of numbers, variables, and operations

   An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations (like +, -, *, /).

3. What does it mean to 'solve' an equation?

   To simplify an expression To find the value(s) of the variable(s) that make the equation true To graph the equation on a coordinate plane To write the equation in a different form

   ✓ To find the value(s) of the variable(s) that make the equation true

   Solving an equation means finding the specific value or values for the variable(s) that satisfy the equality.

4. What is a 'coefficient' in an algebraic term like 5x?

   The variable 'x' The number 5 The operation '+' The entire term '5x'

   ✓ The number 5

   The coefficient is the numerical factor that multiplies a variable in an algebraic term. In 5x, 5 is the coefficient.

5. In algebra, what is a 'constant'?

   A variable that can change A term with a variable A value that does not change A symbol representing an unknown

   ✓ A value that does not change

   A constant is a term in an algebraic expression that has a fixed numerical value and does not contain any variables.

6. What is an 'equation'?

   A mathematical phrase with numbers and variables A statement that two expressions are equal A single number A set of instructions for calculation

   ✓ A statement that two expressions are equal

   An equation is a mathematical statement that shows two expressions are equal, usually connected by an equals sign (=).

7. What does the word 'sum' typically indicate in an algebraic problem?

   Subtraction Multiplication Division Addition

   ✓ Addition

   The word 'sum' indicates the result of an addition operation.

8. If a problem says 'the difference between x and 5', what operation is implied?

   Addition Multiplication Subtraction Division

   ✓ Subtraction

   The word 'difference' implies subtraction. This could be written as x - 5 or 5 - x, depending on context.

9. What algebraic term describes 'twice a number'?

   n + 2 n - 2 2n n/2

   ✓ 2n

   'Twice a number' means multiplying the number (represented by 'n') by 2, which is written as 2n.

10. Which of the following represents 'a number decreased by 7'?

    7 - n n / 7 7n n - 7

    ✓ n - 7

    'A number decreased by 7' means you start with the number (n) and subtract 7 from it, resulting in n - 7.
