  1. 2.8 Literal Equations Objective: Solve equations for given variables Use formulas to solve real-world problems

  2. Solving for a Specific Variable • Get the specific variable on One side of the equation and everything else on the other side

  3. Example Solve for m, x + r = q

  4. ExampleSolve for x ax + 4 = 7

  5. Solve 5a + c = -8a, for a

  6. Solve for h 7h + f = 2h + g

  7. You Try Solve for n, 15=3n+6p

  8. You Try Solve for k,

  9. Example k+m = n, for k -7

  10. Example Solve for x, 7x-2z=4-xy

  11. You Try Solve for d, d+5c=3d-1

  12. The formula for the volume of a rectangular prism is V=lwh, where l is the length, w is the width and h is the height.A) Solve the formula for w.

  13. Dimensional Analysis/ Unit Analysis The process of converting units of measure.

  14. Page 128 – Example 4 A 10 k run is 10 kilometers long. If 1 meter=1,094 yards, use dimensional analysis to find the length of the race in miles. (Hint: 1mi = 1760)

  15. Page 128 # 6 Scott found a rare video game on an online auction site priced at 35 Australian dollars. If the exchange rate is $1 U.S. = $1.24 Australian, find the cost of the game in the United States dollars. Round to the nearest cent.

  16. Homework Page 129 #’s 9-15 odd, 16, 18
