As a first word problem, this one may seem a bit intimidating; don't let it discourage you, though.
You may be surprised at how far you can get by approaching the problem systematically.
Note: we could have also tried "guess and check": And so L = 8 or −14 There are two solutions to the quadratic equation, but only one of them is possible since the length of the room cannot be negative!
Before you start solving word problems in algebra, you should first already know about real numbers, how to manipulate algebraic expressions, and how to solve math problems involving linear equations and inequalities.
The Algebra Class E-course provides a lot of practice with solving word problems for every unit! if you have trouble with these types of problems, you can always find a step-by-step solution to guide you through the process! How long will it be before you and your sister have the same amount of money?
We know there are seven days in the week, so: d e = 7 And she trains 27 hours in a week, with d 5 hour days and e 3 hour days: 5d 3e = 27 We are being asked for how many days she trains for 5 hours: d Solve: The number of "5 hour" days is 3 Check: She trains for 5 hours on 3 days a week, so she must train for 3 hours a day on the other 4 days of the week.
We will focus on application of these concepts through word problems.
First, we'll review a few basic steps that will help you solve word problems.
Here are some steps that will help you organize the process of translating from words to mathematical expressions that you can solve. You may not be able to visualize all the details, but you should gain a mental picture of what is generally being discussed. Thus, figure out what you are trying to find and write it down. If the problem involves a moving automobile, for instance, you don't need to draw a professional rendition when a box or something similar (even marked "car" if necessary) will do. Write down this assignment for reference as you solve the problem (for instance, " = the velocity of the car"). You've probably gone astray somewhere along the line.
Check to see if the number is reasonable (for example, your average automobile can't be expected to go 1,000,000 miles per hour! Before we look at a few example problems, we need to first consider the use of units and unit analysis.
