  1. Write algebraic expressions

  2. Do Now Write the words in the right column 1.Divided by 2. Plus 3. Shared equally 4. Difference 5. in all 6. times 7. More than 8. decreased 9. increased by 10. Product 11. less than 12.greater than 13. each 14. Minus 15.Sum 16. Multiplied by 17. Quotient

  3. Write an algebraic expression for each phrase. 1. Seven more than n n + 7 2. The difference of n and 7 n - 7

  4. 3. The product of seven and n 7n 4. The quotient of n and 7

  5. Define a variable and write an algebraic expression for each phrase. Two times a number plus five. Define a variable. Let n = the number Write. 2n + 5 2 * n + 5

  6. Variable = a symbol, usually a letter, that represents one or more numbers. Algebraic expression = a mathematical phrase that can include numbers, variables, and operation symbols.

  7. Define a variable and write an algebraic expression for each phrase. 9 less than a number The sum of twice a number and 31 A number increased by 3.

  8. Write an algebraic expression for each phrase. 4 more than p The difference of 7 and a number n y minus 15 The quotient of n and 8 23 less than x The product of 3 and a number x

  9. Define a variable and write an algebraic expression for each phrase. 2 more than twice a number A number minus 11 9 minus a number A number divided by 82 The product of 5 and a number 25 more than twice a number m The quotient of a number and 6

  10. the product of 15 and the quantity 12 more than a number x 1. 15 + 12x 2. (15 + 12)x 3. 15(x + 12) 4. 15x 12 +x

  11. A museum charges $50 for an annual membership and then reduced price of $2 per ticket. • Write and expression to represent the situation. • Find the total cost to join the museum and buy 9 tickets.

  12. Write equation and inequalities

  13. What is the difference between expressions and equations/inequalities? Expressions 2x + 5 3x – 6 2x Equations and inequalities 5x + 1 = 6 2x – 5 = 8 X – 13 > 8

  14. Write in the correct columns<, >, =, Is less than Is more than No more than No less than The same as Is equal to Fewer than At most At least

  15. The sum of 42 and a number n is equal to 51 The difference of a number z and 11 is equal to 35 The product of a number b and 3 is no less than 12

  16. The difference of 22 and the quotient of a number m and 4 is 54 • The sum of 7 and three times a number b is at least 12 • 3 less than twice a number n is 12 • The product of 4 and a number w is at most 51

  17. The product of 3 and a number y is no more than 21 • The sum of 13 and a number t is at least 24. • The difference of a number c and 17 is more than 33 • The difference of 9 and the quotient of a number t and 6 is 5
