Math works just like anything else, if you want to get good at it, then you need to practice it.Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument.
The equations in the systems in this tutorial will all be linear equations.
If you need help solving them, by all means, go back to Tutorial 49: Solving Systems of Linear Equations in Two Variables and Tutorial 50: Solving Systems of Linear Equations in Three Variables and review the concepts.
Basically, we are combining the concepts from Tutorial 16: Formulas and Applications, Tutorial 49: Solving Systems of Linear Equations in Two Variables and Tutorial 50: Solving Systems of Linear Equations in Three Variables all rolled up into one tutorial.
We will be looking at different types of word problems involving such ideas as distance, percentages, and something we can all relate to MONEY!!!
Sounds simple enough, but some people jump the gun and try to start solving the problem before they have read the whole problem.
Once the problem is read, you need to list out all the components and data that are involved.(ii) There is a value associated with each quantity: for instance, the price of an adult ticket or a children's ticket, or the number of items in a large box as opposed to a small box.Such problems often require you to write two different linear equations in two variables. To get the most out of these, you should work the problem out on your own and then check your answer by clicking on the link for the answer/discussion for that problem.At the link you will find the answer as well as any steps that went into finding that answer.1c.Hey, lucky you, we have another tutorial on word problems.As mentioned before, whether you like it or not, whether you are going to be a mother, father, teacher, computer programmer, scientist, researcher, business owner, coach, mathematician, manager, doctor, lawyer, banker (the list can go on and on), problem solving is everywhere.Typically, one equation will relate the number of quantities (people or boxes) and the other equation will relate the values (price of tickets or number of items in the boxes). Before you jump into learning how to solve for those unknowns, it’s important to know exactly what these solutions mean.A student has money in three accounts that pay 5%, 7%, and 8%, in annual interest.She has three times as much invested at 8% as she does at 5%.
