Translating Words to Equations: Constants & Variables Quiz

1. Sarah has 5 apples and buys x more apples. Write an equation to represent the total number of apples she has now.

• total_apples = 5 - x

• total_apples = 5 / x

• total_apples = 5 + x

• total_apples = 5 * x

2. A book costs $10, and you want to buy y books. Write an equation to find the total cost of the books.

• total cost = 10 / y

• total cost = 10 * y

• total cost = y - 10

• total cost = 10 + y

3. Tom has 3 times as many marbles as his friend. If his friend has m marbles, write an equation to express how many marbles Tom has.

• T = 4m

• T = 2m

• T = m

• T = 3m

4. A car travels at a speed of 60 miles per hour for t hours. Write an equation to find the total distance traveled by the car.

• Distance = 60 - t

• Distance = 60 + t

• Distance = 60t

• Distance = 60t^2

5. Lisa has $50 and spends x dollars on a toy. Write an equation to find out how much money she has left.

• 50 + x

• x - 50

• 50 - x

• 50 * x

6. A rectangle has a length of 4 meters and a width of w meters. Write an equation to find the perimeter of the rectangle.

• P = 4 + w

• P = 2(4 + w)

• P = 2(4 - w)

• P = 4w

7. If a pizza has 8 slices and you eat y slices, write an equation to find out how many slices are left.

• y - 8

• 8 + y

• 8 * y

• 8 - y

8. A school has 200 students, and x new students enroll. Write an equation to find the total number of students in the school now.

• 200 * x

• 200 / x

• 200 + x

• 200 - x

9. A box can hold 12 items, and you have z boxes. Write an equation to find the total number of items you can store.

• total_items = z + 12

• total_items = 12 - z

• total_items = 12 * z

• total_items = 12 / z

10. If a train leaves the station at 2 PM and travels for h hours, write an equation to find out what time the train arrives at its destination.

• Arrival Time = 12 + h hours

• Arrival Time = 14 + h hours (in 24-hour format) or 2 PM + h hours.

• Arrival Time = 14 - h hours

• Arrival Time = 16 + h hours
