Match Algebraic Equation to Word Problem

Match the word problem with the expression:
A battery box contains 18 batteries.  Every toy needs the same number of batteries.  I was able to replace the batteries in 9 toys.  How many batteries did each toy need?  

• 9 ⋅ u = 18

• 18 - u = 9

• 18 = 9 + u

• 18 ÷ u = 9

• x + 7

• x - 7

Which expression correctly shows "5 less than a number"?

• y + 5

• Four less than twice a number

• 2n-4

• Three times a number minus 5

Match the word problem with the expression:
A teacher had 16 students.  She needed to split up her class into a number of equal groups.  When she was finished, she had 4 groups.

• f x 4 = 16

• 16 x 4 = f

• f = 16 ÷ 4

• 16 ÷ f = 4

Write an equation to match the word problem: After paying $5.12 for a salad, Norachai has $27.10 left. How much money did he have before buying the salad? Let x represent the amount of money Norachai had before buying the salad.

• 27.10/5.12 = x

• 27.10 - 5.12 = x

• x - 5.12 = 27.10

• 5.12 + x = 27.10
