Tutorial 53:
Practice Test on Tutorials 49
- 52
Learning Objectives
|
After completing this tutorial, you should be able to:
-
Take a test on topics covered in tutorials 49 - 52 in this website.
|
| Note that I can not guarantee you will pass
your test after going though any of the tutorials in this website or this
practice test. However, it will definitely help you to understand the topics
covered better.

Introduction
|
| It is important to note that chances are I'm not your math instructor.
You
need to check with your math teacher as to things like when your next math
test is and what it covers. It may cover more material on the test
than what is in this practice test. Just note that there are
other practice tests at this website. So, after finding out what is on
your test (if you have one) do the practice test(s) problems that go with
the test you are preparing for. If you are not in a class or are
not having a test soon, this practice test is still good practice to go
through and check to make sure you are understanding this material before
moving on - kind of like a spot check. The material on this practice
test goes with Tutorial 49: Solving
Systems of Linear Equations in Two Variables, Tutorial
50: Solving Systems of Linear Equations in Three Variables, Tutorial
51: Systems of Linear Equations and Problem Solving, and Tutorial
52: Solving Systems of Nonlinear Equations in Two Variables.
Also note that your teacher may word the problems on their test a
little differently, may have some different kinds of problems, or may have
a different number of problems than what is in this practice test.
Again, since I'm probably not your math instructor, I don't know exactly
how your teacher will set up your math test. Just note that these
problems will help you build an understanding of the concepts presented
and the terms used in math problems. If you have an understanding
of the problems instead of just memorizing them, then you should do fine
on these concepts, no matter how the test is set up.

Steps to Studying for a Math Test
|
-
Work through problems. If you are in a class, you should have
done this on completion of any homework you have done. For anyone,
you can accomplish this by doing the practice problems found in each tutorial.
-
Check work on problems. The practice problems in each tutorial
have links to the answers to them so you can instantly check how you are
doing. Also, in most math books, the odd answers are found in the
back of the book.
-
Review concepts. Whether you got the problems right or wrong,
make sure you review over them. If you did get a problem wrong, make
sure you either review that concept in it's respective tutorial or ask
your math teacher about it. If you don't ask about a problem before
a test, you are going to kick yourself when it comes up on the test.
-
Work through problems as if you were taking the test - no notes, book,
webpages, etc. This practice test is a perfect way to do that.
After
taking this practice test, check your answers by clicking on the link to
the answer key found at the bottom of the practice test (before the 'need
extra help on these topics' section)

It is to your benefit to show as much of the work as possible on
the problems that have several steps involved.
Make sure that you read the directions carefully, you wouldn't
believe how many points get taken off math tests for people not following
directions.
Pace yourself. You do not have to be the first one done
to do well on the test. Do not panic if there is still time left
to take the test and others are turning it in. Sometimes that means
they do not know the material and left some of the answers blank.
Do not worry about anyone else but yourself.
Don't rush through a problem. Another thing that
math teachers take points off for are careless mistakes made by people
that rush through a problem. When those students get their tests
back, they bonk themselves on the head at some of the things that got counted
wrong, things that they knew how to do.
Check your answers. If you have time, go back and check
your answers.
Remember to breathe!!!! I know some of you are scared to
death at the thought of having to take a math test of any kind.
For you guys, try to relax and don't forget to breathe. (Even if
you aren't scared to take a math test, it is probably a good idea to remember
to breathe, I wouldn't want you to pass out during the test)
Good luck on your test. If you are taking a math test soon,
good luck on it. I know you are going to do great!!! |
Practice Test
|
| Problems 1a - 1b: Solve each system by either the substitution
or elimination by addition method. |
1a.
 |
1b.
|
| Problem 2a: Solve the system by either the substitution or
elimination by addition method. |
2a.
 |
| Problems 3a - 3b: Solve the given word problems using systems
of equations. |
| 3a. It took a boat 4 hours to travel downstream 120 miles. Upstream,
the same trip took 6 hours. Find the rate of the boat in still water
and the rate of the current. |
| 3b. A piggy bank contains only nickels, dimes and quarters.
The value of the coins is $5.50. The number of nickels is three times
that of the dimes. The number of nickels is six more than twice the number
of quarters. Find the number of nickels, dimes, and quarters in the
piggy bank. |

or elimination by addition method. |
