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.
So let's draw this garden here, Tina's garden.
So if this is the width, then this is also going to be the width. And they tell us that the length of the garden is twice the width.
This problem illustrates the process of unit conversion; a year is the same as 525,600 minutes even though 1 ≠ 525,600.
Bill takes a trip in which he drives a third of the time at 30 miles per hour, a third of the time at 50 miles per hour, and a third of the time at 70 miles per hour.
If the boiling point of water is and the melting point of water is , find the linear functions that convert from one scale to the other.
This problem asks us to find a conversion function that takes a Fahrenheit temperature reading and turns it into a Celsius temperature reading.
So his normal pay of 40 × = 0, plus his overtime pay of 12 × = 0 gives us a total of 0 There are 12 girls!
And 3b = 4g, so b = 4g/3 = 4 × 12 / 3 = 16, so there are 16 boys So there are now 12 girls and 16 boys in the class, making 28 students altogether.
First, we'll review a few basic steps that will help you solve word problems.
At this point, the mathematical aspects of word problems shouldn't pose much difficulty for you. This is the critical step: translation of the information that you get from the problem into math. Take the results of step 5 and use the algebra skills you've learned to solve the problem. Look at your final answer and ask yourself if it makes sense.
