One Step Real World Equations

Solve the equation
3x = 27. 

• x = 24

• x = 81

• x = 9

• x = 3

x ÷ 2 = 12

• x = 24

• x = 6

• x = 20

• x = 10

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

how would you solve this equation: 9x=153?

• multiply by 9 on both sides

• divide by 9 on both sides

• add 9 to both sides

• subtract 9 from both sides

m - 5 = -10

• -15

• 15

• -5

• 5

5m = 10  solve for m

• 50

• 15

• 5

• 2

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

Which choice models this situation? Lisa finished a race in 58 seconds. This was 4 seconds faster than her best practice time. What was Lindsey's best practice time?

• t + 4 = 58

• t - 4 = 58

• 4t = 58

• t/4 = 58

Which choice models this situation?
Taylor has read 125 pages in a book. The book has a total of 262 pages. How many pages does she have left to read to finish the book?

• p - 125 = 262

• p + 125 = 262

• 125p = 262

• p/125 = 262

Which choice models this situation? Last week, Tina worked 35 hours in 5 days. She worked the same number of hours each day. How many hours did she work each day?

• h - 5 = 35

• h + 5 = 35

• 5h = 35

• h/5 = 35
