Are you ready for SAT Math problems on ratios, proportions, percentages and rates? If you need to review the basics first, check out my previous post for that. Otherwise let’s do some SAT Math example problems. Example Problem 1 A county repairs 5 miles of public roads every month. How long will it be…
SAT Math has a few word problems that involve ratios, proportions and percentages. Understanding this topic well and being able to apply it to real life problems for in SAT Math will get you well on your way to doing successfully on SAT Math. What is a ratio? A ratio is a relationship between the…
SAT Math has at least one question (but good chance more than that) on setting up and solving a system of linear inequalities. This article walks you through solving a system of linear inequalities. A system of two or more linear inequalities is made up of two linear inequalities that cross somewhere on the X-Y…
What is a linear inequality? Think of a linear equation, see the article here, but instead of an equal sign, you have > (more than), < (less than), ≥ (more or equal to) or ≤ (less than or equal to) sign. The best way to show what inequality is and what it means is to…
You will encounter problems on SAT Math where you will have to set up a system of linear equations and/or inequalities in order to solve the problem. While the previous two articles walk you through solving a system of linear equations, and solving a system of inequalities, this article will show you how to set…

A system of two or more linear equations is made up of two linear equations that cross somewhere on the X-Y…
SAT Math is big on real-life word problems, this tests not only your knowledge of the theory about the linear equations, but also your ability to apply that theory. Here is a process for approaching SAT Math word problem: Quickly scan the problem. Decide for yourself if you’re familiar with it enough to spend time…
SAT Math is heavy on linear equations. Knowing this well gives you the basis for the proper set up and solution of the numerous word problems on SAT Math. So let’s go… What is a linear equation? A linear equation is an equation which when plotted makes a line. Below are some of the examples…
You will encounter at least one factoring problem on SAT Math test. This post walks you through how to factor a quadratic equation from an expanded form into the factored form. The expression in the expanded form looks like this X2 + bX + c = 0 But the same expression with factors looks like…
What Is An Algebraic Expression? First off, the word “algebraic” comes from the word “algebra.” Algebra comes from Arabic word “al-jabr,” which means the reunion of broken parts. And “al-jabr” comes from Arabic “jabara”, which means reunite, restore. So “algebra” means the science of restoring what is missing and equating like with like. When you…
