Basic Algebraic Expressions

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

Match the word problem with the expression:
Mr. Furlich had some students visit his office in the morning.  Later he had three more students visit his office.  Altogether, 19 students had visited his office throughout the day.  How many came in the morning?

• 19 - b = 3

• b + 3 = 19

• 3b = 19

• 19 - b

Match the word problem with the expression:
Each day of the week I work the same number of hours.

• 7y

• y + 7x

• 7 ÷ y

Match the word problem with the expression:
At the end of the day, the Girl Scouts had only 15 boxes of cookies left.  They came with a number of boxes and sold 36 throughout the day.  How many did they start out with?

• 36 - d = 15

• 36 + 15 = d

• d = 36-15

• 15 = d - 36

Match the word problem with the expression:
Jacob added 12 pennies to his piggy bank full of pennies.  When he opened it up, he had a total of 42 pennies.  How many did he have in his piggy bank before he added the extra pennies?

• t - 42 = 12

• 42 + 12 = t

• 12 +t = 42

• 12t = 42

Four less than the sum of 7 and 3

• 4 - (7x3)

• (7+3) - 4

• (7x3) x 4

five times the difference of 6 and 2

•  5 x (6-2)

• (6 / 2) -5

• (6x2) - 5

Evaluate the equation:
(10+5) -6

• 9

• 10

• 11

• 12

Which expression matches "25 divided by the difference of 12 and 7"?

• (12 - 7) ÷ 25

• 25 ÷ (12 - 7)

• 25 ÷ (12 + 7)

• (12 + 7) ÷ 25

Which expression matches the statement "18 less than the product of 10 and 7"?

• (10 + 7) - 18

• 18 - (10 x 7)

• (10 x 7) - 18

• 18 - ( 10 - 7)
