Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.  Which system of equations represents the situation?

• 3x + 2y = 315
  2x + 4y = 450

• 3x + 2y = 450
  2x + 4y = 315

• 2x + 2y = 315
  3x + 4y = 450

Solve the equation m + 9.2 = 53    
   

• a. m = 14.5

•  b. m = 43.8

• c. m = 72.3

• d. m = 723 

Solve the equation s – 17 = 54

•  s = 71

•  s = 37

• s = 72

• s = 61 
   d. s = 61 
   d. s = 61
