Slide 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? Slide 18 Algebra: Write Expressions Writing verbal phrases as algebraic expressions. Step 1 Describe the situation using the most important words. Slide 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. Slide 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. Slide 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. Slide 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 Slide 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 Slide 24 Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 1 Describe the situation using the most important words. Slide 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. Slide 26 Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 2 Choose a variable to represent the unknown quantity. Slide 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 Slide 28 Algebra: Write Expressions e.g. Ten dollars less than the original price. Step 3 Convert your verbal phrase into an algebraic expression. Slide 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? Slide 30 Algebra: Write Expressions Four points fewer than the Bulls scored. Do this on your own. Slide 31 Algebra: Write Expressions Four points fewer than the Bulls scored. B 4, B = Points Bulls Scored. Slide 32 Algebra: Write Expressions 12 times the number of feet Do this on your own. Slide 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. Slide 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. Slide 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. Slide 36 Algebra: Write Expressions Write the phrase 5 less than 3 times the number of points as an algebraic expression. Step 2 Choose a variable to represent the unknown quantity. Slide 37 Algebra: Write Expressions Write the phrase 5 less than 3 times the number of points as an algebraic expression. Step 2 Choose a variable to represent the unknown quantity. Let p = number of points Slide 38 Algebra: Write Expressions Write the phrase 5 less than 3 times the number of points as an algebraic expression. Step 3 Convert your verbal phrase into an algebraic expression. Slide 39 Algebra: Write Expressions Write the phrase 5 less than 3 times the number of points as an algebraic expression. Step 3 Convert your verbal phrase into an algebraic expression. 3p 5, p = number of points Generally, the term with a number and variable comes first in an expression. Slide 40 Algebra: Write Expressions Write the phrase $3 more than four times the cost of a pretzel as an algebraic expression. Do this on your own. Slide 41 Algebra: Write Expressions Write the phrase $3 more than four times the cost of a pretzel as an algebraic expression. 4p + $3, p = cost of pretzel Slide 42 Algebra: Write Expressions Shoko bought a box of popcorn for $3.50 and three medium soft drinks. Define a variable and write an expression to represent the total amount he spent. Then find the total amount if one drink costs $1.50. Do this on your own. Slide 43 Algebra: Write Expressions Shoko bought a box of popcorn for $3.50 and three medium soft drinks. Define a variable and write an expression to represent the total amount he spent. Then find the total amount if one drink costs $1.50. 3d + 3.5, d = drink 3 1.5 + 3.5 4.5 + 3.5 8 Slide 44 Algebra: Write Expressions Terri bought a magazine for $5, and 2 bottles of nail polish. Write an expression to represent the total amount she spent. Then find the total amount if each bottle of nail polish costs $3. Do this on your own. Slide 45 Algebra: Write Expressions Terri bought a magazine for $5, and 2 bottles of nail polish. Write an expression to represent the total amount she spent. Then find the total amount if each bottle of nail polish costs $3. 2d + 5, d = cost of bottle of nail polish 23 + 5 6 + 5 11 Slide 46 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: n + 7 Slide 47 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: n + 7 7 more songs Slide 48 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: n - 2 Slide 49 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: n 2 2 less songs Slide 50 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: 4n Slide 51 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: 4n 4 times the songs Slide 52 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: n 2 Slide 53 Algebra: Write Expressions If n represents that number of songs stored on an mp3 player, describe the meaning of: n 2 Half the songs Slide 54 Algebra: Write Expressions How can writing phrases as algebraic expressions help you solve problems?
