The perimeter of a rectangular garden is 38 feet. The width, w of the garden is two units less than twice the length, l. Which of the following systems of linear equations could be used to determine the dimensions of the garden?

• l + w = 38

  w = 2l − 2

• 2l + 2w = 38

  w = 2l − 2

• 2l + 2w = 38

  l = 2w + 2

• 2l + 2w = 38

  w = 2l + 2

The Johnson family is planning a trip to Six Flags. There are a total 9 people, both adults and children, in the Johnson family who will be going on the trip. The cost per adult ticket is $25 and the cost per child ticket is $17.50. The Johnson family spends a total of $180 to purchase their tickets. Which of the following systems of equations can be used to determine the number of adults, a and children, c in the Johnson family who are going to Six Flags?

• a + c = 180

  25a + 17.50c = 180

• 25a + 17.50c = 9

  a + c = 9

• a + c = 9

  25a + 17.50c = 180

• a + c = 9

  17.50a + 25c = 180

The graph shows a system of linear equations. Which of the following could be used to determine the solution?

• 3x − 2y = 8

  7x + 4y = −28

• 3x + 2y = −8

  7x − 4y = 28

• 3x + 2y = 8

  7x − 4y = −28

• 3x − 4y = 28

  7x + 2y = −8
