Solve the equation:

3x - x + 4 = 4(2x +1)

• no solution

• infinite solutions

• x = 6

• x = 0

²/₃(5x + 6) = 34

• 51
• 45
• 8
• 9

Solve  -(1 + 7x) - 6(-7 - x) = 36

• x = 10
• x = -10
• x = -5
• x = 5

10 less that half a number is equivalent to 8.  

• 10 - 1⁄2x = 8 
• 1⁄2x + 10 = 8
• 1⁄2x - 10 = 8
• 10x - 0.5 = 8

If 37 less than the product of 15 and a number is 38, which of the below items is true?

• The solution is -5.
• The solution is 60.
• The equation is
  37 - 15x = 38
• The equation is
  15x - 37 = 38

Justin is purchasing a new iPhone.  The sales clerk says that if he pays $100 now his monthly payments will be $25 and his total cost will be $600.  Which equation can be used to determine how many months Justin will be paying for his phone? 

• 25x + 100 = 600
• 25x - 100 = 600 
• 600 - 100x = 25
• 600 + 25x = 100 

Twice the difference of a number and 16 is equivalent to 28. 

• 2x + 16 = 28
• 2x - 16 = 28 
• 2(x + 16) = 28 
• 2(x - 16) = 28

pV = nRT
solve for R

• R= pV/nT
• R= p/n + V/T
• R= pV - nT
• R= (pV-n)/T
