I will give students a few minutes to read the problem to themselves and highlight the important information, before we discuss it as a class.

Although students should show the work to the problems below in their own notebook, I will encourage students to discuss them with their group. I multiplied the total number of pounds in the mixture 30 by the minimum and maximum percentages 46% and 50% , respectively. Choose the correct solution interval for each problem.
Removing parentheses does not mean to merely erase them. . Example 2 - Giselle has been babysitting to save money for a cell phone. To make things easier, we test positive integers. We have to remember to make it a dotted line when it is strictly greater than, so we can go ahead and erase little bits of the line to make this a dotted line.
The best way to learn this is by example, so let's try our first example: Sam and Alex play in the same soccer team. Inequalities - Introduction Inequalities are all around us. Find the yearly rate when the amount of interest, the principal, and the number of days are all known. Step 2: Identify your variable. Here is a common mistake:. His average running speed is half of his average cycling speed.
Most inequalities of this type are only for positive numbers, and this type of inequality often has extremely clever problems and applications. Giselle will need to work for at least six hours to save enough money, but she must work less than 16 hours this week. During the weekend, she plays four matches, winning three and losing one. Solve and graph the inequality. To figure out which side of the boundary is the greater than side, we can substitute in a test point and see if it works. Then there would be no boys at all, and the question isn't clear on that point sometimes questions are like that. Compare the solution with that obtained in the example.
I am so happy to have had the experience of starring in an original cast for a world premiere show. Example 1 - Kelly works for Quick Oil Change. I'll set it up the same way, though: pounds % copper pounds copper 60% x 0. We will start with an intuitive solution, and then a rule can be built for solving general fractional inequalities. Some of them might be so familiar that you don't even notice them. What must be done when dividing by a negative number? The question verifies that you don't know how many weeks.
Keep these handy as a reference. After more of this type of work, we realize that brings about division by , so it certainly isn't a solution. But now, because there are multiple inequalities in one problem, we need to put the other ones on the same set of axis as this one. The type of inequality in this problem can be deceiving because there's only one variable, but when the problem gives us restrictions on y, it implies that x can be whatever we want. This ticket out will give you a good sense of where your students are both in terms of inequalities but also in terms of algebraic representations in general.
After 5 minutes, I will randomly select students to show their work on the board. To get rid of 7, we have to multiply by 7 on both sides and solve the inequality as explained below. Section 2-11 : Linear Inequalities For problems 1 — 6 solve each of the following inequalities. Give the solution in both inequality and interval notations. Equations and Inequalities Involving Signed Numbers In chapter 2 we established rules for solving equations using the numbers of arithmetic.

Example 4 - 6 4 on the number line. Take a look at the questions that other students have submitted:.
The question verifies that you don't know the number of miles Katie can travel. What are two inequalities we can use to represent the situation? This will allow students to see how changing the wording of an inequality changes its' solution set. Last Saturday Alex scored 3 more goals than Sam, but together they scored less than 9 goals. That wasn't too bad, was it? Finally, taking into account that it's a system of inequalities, our solution is, again, only the region where this new shading intersects the shading from the previous two inequalities. Click the following link to download solving one step inequalities -worksheet as pdf document. However, one important note is, if we multiply the whole inequality by a negative number, we have to flip the inequality sign. An example for real numbers is the so-called , which states that for any real ,.
