• total_apples = 5 / x

2. If a book costs $15 and you have y dollars, write an equation to find out how much money you need to buy the book.

• 15 + y

• y - 15

• y / 15

• 15 - y

3. A rectangle has a length of 10 cm and a width of x cm. Write an equation to express the perimeter of the rectangle.

• P = 2(10 + x)

• P = 2(10 - x)

• P = 2(10 + 10)

• P = 10 + 2x

4. Tom has 12 marbles. He gives away m marbles to his friend. Write an equation to show how many marbles Tom has left.

• m - 12

• 12 * m

• 12 + m

• 12 - m

5. A car travels at a speed of 60 miles per hour. If it travels for t hours, write an equation to find the distance traveled.

• distance = 60t^2

• distance = 60 + t

• distance = 60t

• distance = 30t

6. Lisa has 20 stickers. She gives away s stickers to her friends. Write an equation to find out how many stickers she has now.
