Date:Use Inequality SymbolsAn inequality expresses a relationship between numbers or quantities. Two inequalitysymbols are < and >.5 < 6 means 5 is less than 6. This same information 0 1 2 3 4 5 6 7 8can also be shown as 6 > 5, which means 6 is greater than 5.4. Use both the less than, , symbols to write twoexpressions showing the relationshipbetween the given numbers.5. List the whole numbers that satisfyeach statement.a) x < 4a) 1 and 7b) between 4 and 8b) 4 and -1c) 3 and 3.5c) t > 11d) 0 and 1d) a < 15Solve EqualitiesWhen you are asked to solve an equation, you are being asked to find all values foran unknown that make a true statement.Solve 2x - 1 = 7.Solution2x - 1 + 1 = 7 + 12x = 8x = 4Check:2(4) - 1 = 78 - 1 = 77 = 76. Solve each equation and then verify your answer.a) x + 4 = 6 b) -2x + 1 = 9c) -5x - 3 = -8 d) 4x + 9 = 21Get Ready • MHR 3
