September 6, 2011 By the end of today: I will know how to write equations and inequalities from a given word problem and turn a word problem into an equation/inequality. Have your composition notebook on your desk open to your homework.

9/2 Homework: Worksheet 1.) 6n – 4 7.) Two less than 3 times a number k 2.) 5/y 8.) Four times the sum of m and six 3.) 4(4 – t) 9.) Eight more than one third of a number a 4.) 3(7 + k) 10.) Six more than twice a number c 5.) 4k – 1 11.) 9x7y2z – nine times x to the seventh power times y squared times z 6.) x2 + y3

Words That Mean… Equals Less than Greater than Less than or equal to Greater than or equal to

Be Very Careful! What does “5 less than 10” mean? What does “5 is less than 10” mean? That word “is” IS important!

Expression, Equation, or Inequality? An equation always has an equal sign. An inequality always has a <, >, <, > sign. An expression has NO symbol.

Write the Equation or Inequality The difference of twice a number k and 8 is 12 The product of 6 and a number n is less than 24 6 less than x is 10

Write the Equation or Inequality The sum of 42 and a number n is equal to 51 The product of 8 and a number k is greater than 4 The product of 9 and the quantity 5 more than a number t is less than 6

Write the Verbal Rule x + 8 = 13 15 – 4y > 6 3(f – 6) = 4
