The stocks were not worth the same amount in the beginning, so if each stock loses half its value, the new values will not be equal either.

Identify the intersection of the two inequalities and answer the questions that pertain to the problem. Write words to describe the inequality, then math symbols to represent the speed. How many hot dogs were sold and how many sodas were sold?

Dec 02, · This video is about Writing and Graphing Inequalities. Using the inequality in this task, demonstrate how this idea can be used in the process of solving. Suggest using two steps to multiply both sides of C by (e.g., by first multiplying both sides of the inequality by five, then dividing each side of the inequality by nine).

B) Have students write each of the following inequalities one at a time as you give them. Have them guess a reasonable solution and write their guess. Then ask them to replace the inequality symbol with an equal sign and solve the equation using inverse operations.

Steps for Solving a System of Inequalities Word Problem. Read the problem and highlight important information.

Identify the variables. Find one piece of information in the problem that you can use to. The graph shows an arrow beginning on 5 with an open circle and pointing to the left, thus that portion of the graph says, all real numbers less than 5. There is a second arrow beginning on 9 with a closed circle and pointing to the right, representing all real numbers greater than or equal to 9.
