Writing Equations & Independent/Dependent Variables

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?

At Pierce County Middle School, there are 5 art classes with 24 students in each class. How many students altogether are in the art classes?

• s - 5 = 24

• s + 5 = 24

• 5s = 24

• s/5 = 24

Write an equation models the following statement:
 17 less than h equals 42

• 17-h=42
• h-17=42
• h+17=42
• 17+h=42

What equation is modeled?

• 2x -6 = 13

• x + 6 = 13

• 6x = 13

• x - 6 = 13

What equation is modeled?

• 2x = -4

• 2x = 4

• 2+x = 4

• x+2=4

Which choice models this situation?

Last week, James worked 35 hours in 5 days on the farm. He worked the same number of hours each day. How many hours did he work each day?

• h - 5 = 35

• h + 5 = 35

• 5h = 35

• h/5 = 35

Translate the statement into an equation:
Five less than a number is 6

• n - 5 = 6
• 5 - n = 6

Translate the sentence into an equation.
Seven subtracted from n is 18 

• n + 7 = 18
• 7 - n = 18
• n - 7 = 18
• n + 7 = 18n

Write an equation that represents the following:
The quotient of 440 and a number is 220

• 440 - n = 220
• n - 440 = 220
• 440 / n = 220
• n / 440 = 220

twice a number is the same as 36

• x + 2 = 36

• x - 2 = 361

• 2x = 36

• x/2 = 36
