Sometimes an application requires the solution to be a whole number, but the algebraic solution to the inequality is not a whole number. Suppose the unknown number is represented by the variable k. Lets put this on a diagram to make a sense of it. ) Solution: Similarly, the word ratio means division. 0000000016 00000 n 55, x up to 8 regions on the one graph. Let c be the unknown number, the algebraic expression for the math phrase above can be written as. 90, 5 without changing the solution set.). Of course, whenever you multiply a number by 1, the product will be equal to the original . y 5 Math, like any other language, has a way of communicating ideas. 0000001190 00000 n 1 x q 14 Solve Equations Using the Division and Multiplication Properties of Equality. The advanced We do that by putting a bracket at x=1.x=1. 46 Example 1: Write an algebraic expression for the math phrase 3 more than twice a number. ( x + 2 = 8: The difference between a number and seven is negative three. This eliminates negative coefficients and so we dont have to multiply or divide by a negativewhich means we dont have to remember to reverse the inequality sign. 41, w 8 Solve the inequality 13a18a>524a+34,13a18a>524a+34, graph the solution on the number line, and write the solution in interval notation. following properties of inequality. ) = 0000003842 00000 n The average weight of the 25 people on the water taxi when it sank was 168 pounds per person. 0000007889 00000 n Example 2: The difference of triple a number and 5. 0000006743 00000 n 15 other sets written in interval notation are shown below. Solve the inequality 6u+8(u1)>10u+326u+8(u1)>10u+32, graph the solution on the number line, and write the solution in interval notation. = This is the last number to multiply so write the whole number answer. His monthly expenses are $1,100. x = For example: Notice that the inequality sign stayed the same. = y 1 3, 0.25 = For example, the phrase. z 5 14 What is the maximum number of people Daniel can have at the party? > y + used to show that a number is part of the graph, and a parenthesis is used to + 12 75, q At JBs Bowling Alley, 6 people can play on one lane for $34.98.
