A drummer and a guitarist each wrote songs for their band. The guitarist wrote 8 fewer than twice the number of songs that the drummer wrote. They wrote a total of 46 songs.

Which system of equations models this situation if the drummer wrote d songs and the guitarist wrote g songs?

• g = 2d - 8

  g + d = 46

• g = 8 - 2d

  g = 46 - d

• d = 2g - 8

  d = 46 - g

• d = 8 - 2g

  d + g = 46

The perimeter of rectangular box is 18 inches and the width is five inches less than the length. If W=width of the box and L=length of the box, which system of equations matches the situation?

• L + W = 18
  W = L - 5
• 2L + 2W = 18
  L = W - 5
• 2L + 2W = 18
  W = L - 5
• 2L + 2W = 18
  W = 5 - L

12) The school store sells t-shirts and sweatshirts each Friday.

Sales totaled $565.00 last Friday.

Let t represent t-shirts, which sold for $10 each.

Let w represent sweatshirts, which sold for $25 each.

Which equation using t and w represents the total sales for last Friday?

• 10w + 25t = 565

• 10t + 25w = 565

• t + w = 565

• 565t + 10w = 25
