Q.

Which equation matches the following situation? 331 students went on a field trip. Six buses were filled and 7 students traveled in a car. How many students were in each bus?

n= # of students in each bus; 6n + 7 =331

n=# of buses; 6n + 7 =331

n= # of students in each bus; 6 + 7n =331

n= # of students in each bus; 6n - 7 =331

• Question 2

Q.

A taxi charges \$3, plus \$1.50 for each mile traveled. Mr. Maxwell rode in the taxi from his home to the airport and was charged \$30. How many miles does Mr. Maxwell live from the airport? (Write an equation first and solve)

18 miles

20 miles

22 miles

• Question 3
30 seconds
Q. You bought a magazine for \$5 and four erasers. You spent a total of \$25. How much did each eraser cost?  (Define 'n' and write the equation.)
n=total cost of erasers; 5 + 4n = 25
n=cost of 1 eraser; 5 - 4n = 25
n=cost of 1 eraser; 5n + 4 = 25
n=cost of 1 eraser; 5 + 4n = 25
• Question 4
30 seconds
Q. Bonnie spent half of her weekly allowance playing mini-golf. To earn more money her parents let her wash the car for \$4. What is her weekly allowance if she ended with \$12?  (Define 'n' and write the equation.)
n=wkly allowance; 2n-4=12
n=wkly allowance; 2n+4=12
n=wkly allowance; n/2-4=12
n=wkly allowance; n/2+4=12
• Question 5
180 seconds
Q. Speedy Boat Rental charges a \$15 deposit fee plus \$2 for each hour of use to rent a paddle boat.  Write an equation to find out how many hours, h, they rented the Boat if the total cost was \$33.
h = 2(9) + 15
33 = 15h + 2
h = 15(9) + 2
33 = 2h + 15
• Question 6
120 seconds
Q. Twice a number plus 6 is -72
2 + 6x =- 72
2x + 6 = -72
2 + 6 = x
2x2 + 6 = 72
• Question 7
120 seconds
Q. Ken is thinking of a number. Nine more than the product of 4 and the number is 73. What is the equation?
4 + 9x = 73
4x = 73
4x + 9 = 73
9x + 4 = 73
• Question 8
900 seconds
Q. What is the first step to solve this equation:
11 - 3x = 44
Subtract 11 from both sides
Divide 3 on both sides.
• Question 9
900 seconds
Q. The steps in solving 5b - 6 = 24 are:
Add 6 to both sides and divide both sides by 5
Add 6 to both sides and multiply both sides by 5
Subtract 6 from both sides then multiply both sides by 5
Subtract 6 from both sides then divide both sides by 5
