Lesson 11 Practice-

Writing systems of equations for a word problem.

Multiple Choice

Select the system of equations that can be used to determine the number of hours Pressley worked.

• 12 x + 18 y = 144

  x = 2y

• 18 x + 12y = 144

  x = 2y

• 12x + 18 y = 144

  y= 2x

• 18x + 12 y = 144

  y= 2x

Multiple Choice

How many hours did Pressley spent working as a lifeguard (x- value)?

• 6 hours

• 3 hours

• 8 hours

• 0 hours

Multiple Choice

The cost of 5 squash and 2 zucchini is $1.32. Three squash and 1 zucchini cost $0.75. Write a system of equations.

• 5q + 2z = 1.32
  1z = 0.75
• 5q + 2z = 1.32
  3q + 1z = 0.75
• q + z = 1.32
  q + z = 0.75
• 5q + 2z = 0.75
  3q + 1z = 1.32

Algebra 1 unit 6 lesson 5 practice- Graphing Two variable inequalities

Multiple Choice

Your family goes to a southern style restaurant for dinner. There are 6 total people in your family. Some order chicken for $14 and the rest order steak for $17. The total bill is $99. Write a system that could represent this situation.

• c + s = 6

  14c + 17s = 99

• c + s = 99

  14c + 17s = 6

• c + s = 6

  17c + 14s = 99

• c + s = 99

  17c + 14s = 6
