Equation & Inequality RSPQ

​(remarkably similar practice quiz)

This is your practice test.

Work it as many times as you need to be confident in the problems you will get tomorrow.

​Remember to Ask Questions.

​Writing Equations

​Remember that you are looking at your trigger words.

Multiple Choice

Translate the following sentence into an equation:

The sum of 6 times a number and -5 is -8

1

6n+(−5)=−86n+\left(-5\right)=-8  

2

6(n+(−5))=−86\left(n+\left(-5\right)\right)=-8  

3

6n +5=−86n\ +5=-8  

4

−5n+(−6)=−8-5n+\left(-6\right)=-8  

4

Multiple Choice

Translate the following sentence into an equations:

Five less than one-half a number is 83

1

12n−5=83\frac{1}{2}n-5=83  

2

−12n+5=83-\frac{1}{2}n+5=83  

3

5−12n=835-\frac{1}{2}n=83  

4

5n−12=835n-\frac{1}{2}=83  

5

​Solving Equations

​Ask yourself:

  1. ​What is the variable?

  2. ​What's happening to the variable?

  3. ​What's the opposite?

  4. ​Do it (to both sides)

  5. ​Is my variable alone?

  6. ​Yes - Check your answer

  7. ​No. - Go back to step 2.

​Writing and Solving Equations
  • ​When writing two-step equations you will have a term that is constant and a term that is variable (changing).

  • Again, look for trigger words. Of means multiply and is means equals.

​Absolute Value Equations
  • ​| absolute value | is a distance and is ALWAYS postive!

  • | absolute value | brackets are in the family of parentheses, so you want to get them alone.

  • ​Once you have them alone, set the stuff inside | x | equal to both the positive and negative solution and solve.
