• -
• =
• x

2. Cheryl gets paid $8 per hour for her job at the record store.  She made a total of $96 last week.  Which equation models this situation?

• 96h = 8
• h/96 = 8
• 8h = 96
• h/8 = 96

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

5.  After dropping 5ºF, the temperature was 37ºF.  Which choice models this situation?

• d - 37 = 5
• d + 5 = 37
• d - 5 = 37
• d + 37 = 5

A number minus 9 is twelve.

• x - 9 = 12

• 9 - x = 12

• x - 9 = 13

• 9 - x = 14

Five less than a number n is thirty four.

• 5 - n = 36

• n - 5 = 35

• 5 - n = 34

• n - 5 = 34

Jo is thinking of a number. Four less than 9 times the number is 176. How could I find Jo's number?

• 9x - 4 = 176
• 4 - 9x = 176
• 9x + 4 = 176
• 4x + 9 = 176
