Basic Algebraic Expressions and Equations

Match the written expression to its algebraic expression. Remember multiplication can be shown by writing the known number next to the variable and the ' sign shows division. 7 minus n 7-n p divided by 7 p 3 is added to p 3+p 5 times q 5q Take away 6 from g g-6 9 less than b b-9 Sum of n and 5 n+5 5 is subtracted from y y-5 6 divided by q 6 Sum of 4 and p 4+p Choose the algebraic equation that matches the word problem. Mike had RM23 . He washed cars over the weekend and now has RM90 How much money did he make washing cars? 23 + x = 90 There were 16 bales of hay in the barn. Keith stacked more bales in the barn today. Now there are 93 bales of hay. How many bales did he store in the barn? 16 + x = 93 Sally is baking a cake. The recipe calls for 9 cups of flour. She already put in 4 cups. How many more cups does she need to add? 9 - 4 = x After paying RM8 for a pie, Mary has RM50 left. How much money did she have before buying the pie? x - 8 = 50 How many digital movie downloads can you buy with RM150 if each one costs RM15? 150 = x Solve the following algebraic equation. Be sure to show your work. Mike found 44 seashells on the beach. Sally found some more. Together they have 75 seashells. How many seashells did Sally find?
