Complete the following questions to practice the skills you have learned in this lesson.

  1. Translate to an equation: Which equation means nine more than x is equal to 52?
  1. 52 x = 9
  2. 9 − x = 52
  3. 9 x = 52
  4. x + 9 = 52
  1. Translate to an equation: Which equation means ten less than m is −14?
  1. − 14 − m = 10
  2. m − 10 = − 14
  3. m − 10 = 14
  4. 10 − m = − 14
  1. Translate to an equation: Which equation means the sum of y and −30 is 40?
  1. y + ( − 30 ) = 40
  2. y + 40 = − 30
  3. y = 40 + ( − 30 )
  4. − 30 y = 40
  1. Translate to an equation: For a family birthday dinner, Celeste bought a turkey that weighed 5 pounds less than the one she bought for Thanksgiving. The birthday turkey weighed 16 pounds. Which equation represents how much the Thanksgiving turkey weighed?
  1. − x + 5 = 16
  2. x + 5 = 16
  3. x − 5 = 16
  4. 5 − x = 16
  1. Translate to an equation: Which equation represents 45% of 120?
  1. x = 45 + 120
  2. x = 0.45 ( 120 )
  3. x = 4.5 ( 120 )
  4. x = 45 ( 120 )
  1. 250% of 65 can also be written as:
  1. x = 250 ( 65 )
  2. x = 25 ( 65 )
  3. x = 0.25 ( 65 )
  4. x = 2.5 ( 65 )
  1. Translate to an equation: Geneva treated her parents to dinner at their favorite restaurant. The bill was $74.25. Geneva wants to leave 16% of the total bill as a tip. How much should the tip be?
  1. t = 16 + ( 74.25 )
  2. t = 1.6 ( 74.25 )
  3. t = 0.16 ( 74.25 )
  4. t = 16 ( 74.25 )
  1. Large cheese pizzas cost $5 each, and large one-topping pizzas cost $6 each.
    Choose the equation that represents the total cost, T , of c large cheese pizzas and d large one-topping pizzas.
  1. T = 6 c − 5 d
  2. T = 5 c − 6 d
  3. T = 5 c + 6 d
  4. T = 6 c + 5 d
  1. Jada plans to serve milk and healthy cookies for a book club meeting. She is preparing 12 ounces of milk and 4 cookies per person. Including herself, there are 15 people in the club. A package of cookies contains 24 cookies and costs $4.50. A 1-gallon jug of milk contains 128 ounces and costs $3. Let n represent the number of people in the club, m represent the ounces of milk, c represent the number of cookies, and b represent Jada’s budget in dollars.

    2. Select three of the equations that could represent the quantities and constraints in this situation.

  1. m = 12 ( 15 )
  2. 3 m + 4.5 c = b
  3. 4 n = c
  4. 4 ( 4.50 ) = c
  5. b = 2 ( 3 ) + 3 ( 4.50 )
