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

What is the proper way to set up the equation to begin solving?

y = 6x − 11

−2x − 3y = −7

• -2(-11) -3y= -7

• -2(6x-11) -3y = -7

• -2x -3(11) = -7

• -2x - 3(6x-11)= -7

Yesterday a chef used 68 eggs to make 8 chocolate souffles and 10 lemon meringue pies. The day before, he made 7 chocolate souffles and 10 lemon meringue pies, which used 62 eggs. How many eggs, does each dessert require? If (x) represents chocolate souffles and (y) represents lemon meringue pies, give the correct system of equations and the solution as an ordered pair.

• 8x + 10y = 68

  7x + 10y = 62

  ( 2, 6 )

• 8x + 10y = 68

  7x + 10y = 62

  ( 6, 2 )

• 7x + 10y = 68

  8x + 10y = 62

  ( 5, 4 )

• 7x + 10y = 68

  8x + 10y = 62

  ( 5, 3 )

Bob bought a total of 20 pounds of grass seed at the nursery for $128. He paid $9 per pound of Kentucky bluegrass (k) and $6 per pound for Tall Fescue (f). Which system of equations can be used to find the amount of each that Bob purchased?

• k + f = 168

  9k + 6f = 20

• k + f = 168

  6k + 9f = 20

• k + f = 20

  9k + 6f = 128

• k + f = 20

  6k + 9f = 128
