At a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for 2 tacos and 3 small glasses of milk is $5.15. If a system of equations is written, which would be the correct representation of the 2 variables? (In other words, how should the variables be defined?)

• t: # of tacos

  m: # of glasses of milk

• t: Cost of each taco

  m: Cost of each glass of milk

• t: total cost

  m: # of food items

• t: Cost of each glass of milk

  m: Cost of each taco

The length (y) of a rectangle is equal to triple the width (x). The perimeter of the rectangle is 86 centimeters. Which system of equations could be used to solve for the length and width of the rectangle?

Choose the correct ordered pair to represent the system of equations.

• (15, 21)

• (17, 19)

• (14, 22)

• (13, 23)

5)

• P + W = 158

  P – W = 112

• P + W = 158

  P + W = 112

• P – W = 158

  P + W = 112
