  1. 4-3 Solving Multiplication Equations Standard : PFA Indicator: P9 (same as 4-2)

  2. Your goal for every equation… Use the… (or opposite operation) Keep the equation… Show every… To Isolate the variable Inverse operation Balanced Step! Important Steps to Remember!

  3. What is the inverse of multiplying? Dividing Examples 1) -2.5b = 40.5 -2.5b = 40.5 -2.5 -2.5 b = -16.2 Check -2.5 × (-16.2) = ??

  4. 2) 42 = -3f 42 = -3f -3 -3 -14 = f Check: -3 × -14 = ???

  5. Use the formula d = rt to solve the following. A car traveled 300 miles. If its average speed was 65mi/hr how long did it take? • d = rt • 300 = 65 t • 65 65 • 48/13 = t • Or 4.6 t • So, the car traveled about 4.6 hours

  6. Homework • 4-3 • Pg. 162-163 • #4-13 All • # 14-26, 32-36 even only • #38, 39
