  15. Thursday, Nov 21 Lesson 6.4 Algebra: Write Expressions

  16. Algebra: Write Expressions Objective: To understand how to write verbal phrases as simple algebraic expressions.

  17. Algebra: Write Expressions At the end of this lesson you should be able to answer the following question. How can writing phrases as algebraic expressions help you solve problems?

  18. Algebra: Write Expressions Writing verbal phrases as algebraic expressions. Step 1 – Describe the situation using the most important words.

  19. Algebra: Write Expressions Writing verbal phrases as algebraic expressions. Step 1 – Describe the situation using the most important words. Step 2 – Choose a variable to represent the unknown quantity.

  20. Algebra: Write Expressions Writing verbal phrases as algebraic expressions. Step 1 – Describe the situation using the most important words. Step 2 – Choose a variable to represent the unknown quantity. Step 3 – Convert your verbal phrase into an algebraic expression.

  21. Algebra: Write Expressions e.g. Eight dollars more than Ryan earned. Step 1 – Describe the situation using the most important words. This is already condensed to the most important words.

  22. Algebra: Write Expressions e.g. Eight dollars more than Ryan earned. Step 2 – Choose a variable to represent the unknown quantity. Let R = Ryan

  23. Algebra: Write Expressions e.g. Eight dollars more than Ryan earned. Step 3 – Convert your verbal phrase into an algebraic expression. R + 8, R = amount Ryan earned

  24. Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 1 – Describe the situation using the most important words.

  25. Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 1 – Describe the situation using the most important words. Ten dollars less than the original price.

  26. Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 2 – Choose a variable to represent the unknown quantity.

  27. Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 2 – Choose a variable to represent the unknown quantity. Original price = p

  28. Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 3 – Convert your verbal phrase into an algebraic expression.

  29. Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 3 – Convert your verbal phrase into an algebraic expression. p - $10, p = original price Why would it not be $10 - p?

  30. Algebra: Write Expressions Four points fewer than the Bulls scored. Do this on your own.

  31. Algebra: Write Expressions Four points fewer than the Bulls scored. B – 4, B = Points Bulls Scored.

  32. Algebra: Write Expressions 12 times the number of feet Do this on your own.

  33. Algebra: Write Expressions 12 times the number of feet 12f, f = feet Generally, when a number is multiplied by a variable, the number is written first.

  34. Algebra: Write Expressions Write the phrase 5 less than 3 times the number of points as an algebraic expression. Step 1 – Describe the situation using the most important words.

  35. Algebra: Write Expressions Write the phrase 5 less than 3 times the number of points as an algebraic expression. Step 1 – Describe the situation using the most important words. 5 less than 3 times the number of points.
