3.3 solve multi step equations - day 2

  1. 1. • Day Two of Section 3.3 Decimal Equations Word Problems Perimeter Problems
  2. 2. Students will solve multi-step equations using different transformations.• Decimal Equations 2.5 + 1.9x + (-3.9) = 7
  3. 3. Students will solve multi-step equations using different transformations.• Solve: 1.6 = 7.6 - 5(x + 1.1)
  4. 4. Students will solve multi-step equations using different transformations.• Find the value for x if the P = 51 ft 5(x-4) ft 2x – 3 ft How long is each side of the x + 10 ft triangle?
  5. 5. • You helped a friend move a short distance. The friend rented a truck for $15 per hour and rented a dolly for $5. Your friend paid a total of $80 for the rental. How long did your friend rent the truck?• 5 hours
  6. 6. Students will solve multi-step equations using different transformations.• You are driving to a vacation spot that is 1500 miles away. Including rest stops, it takes you 42 hours to get to the vacation spot. You estimate that you drove at an average speed of 50 miles per hour. How many hours were you not driving?• 12 hours
  7. 7. • Assignment: P. 151 (#27, 28, 33,34,38- 40)• Make sure you show all steps and that you check the answer back into the equation.• Quiz tomorrow over 3.1—3.3.
  8. 8. • Take Quiz – please check each problem! Read the next section – 3.4 Variables on Both Sides of the Equation• Be ready to help explain section 3.4 tomorrow. What 2 unique answers can happen with variables on both sides?
