Writing linear equations word problems

How many prescriptions did she have for tranquilizers? Answer the question in the problem The problem asks us to find how many hours Karen needs to work. Calculate the slope from the y-intercept to the second point.

We will use the approximation here.

So her salary before taxes and insurance will be 6h. The examples done in this lesson will be linear equations. Find the lowest grade. Assign a variable for the lowest test grade.

So what should you do?

Study Guides and Strategies

This tells us the highest grade is. Now we can set up the equation Step 5: An example of this type of problem is: Answer the question in the problem The problem asks us to find out how far Rhonda and Jamie drove. The easiest way to explain this would be using an example. On an algebra test, the highest grade was 42 points higher than the lowest grade.

One-step equations — word problems One-step equations can also be communicated in the form of word problems. Now we have our system of two equations. We are told 6 is added to 4 times a number.

Algebra Quiz

We will do that by dividing the whole equation by 4. If your teacher wants you to leave as part of your answer, you should ask how to do that.

The sum of a number and 9 is multiplied by -2 and the answer is We know that Jamie drove twice as far a Rhonda. If Rhonda drives 10 miles, then Jamie will drive twice as far which would be In some classes your teacher may want you to leave in its exact form rather than approximating the value as 3.

For example, if you are being asked to find a number, some students like to use the variable n. That means we need to add 42 to the lowest grade. Therefore, it is important that you feel comfortable using them. The formula for the circumference is.

Writing Linear Equations

For how many hours did she rent the bike? This is where most students feel they have the most trouble. Find the radius of the face.Solve various word problems that involve real world relationships that can be represented by linear equations or functions. Do you get confused when you have to write linear equations?

Don't worry, that's about to change! In the previous unit, Graphing Equations you learned how to graph linear equations on a coordinate grid. In this unit, we are going to reverse that process and write equations to match a graph or a word problem.

This unit is very important. Practice writing equations to model and solve real-world situations. Free Algebra 1 worksheets created with Infinite Algebra 1. Printable in convenient PDF format. Algebra Quiz: Test your algebra skills by answering questions.

This quiz asks you to solve algebraic linear and quadratic equations of one variable.

Most of the time when someone says “word problems” there is automatic panic. But word problems do not have to be the worst part of a math class.
