  1. Bell Ringer Mahnoor ate four more than one-half the number of chickens Chris ate. If Mahnoor ate nine chickens, how many did Chris eat? c + 4 = 9 – 4 – 4 c = 5 c = 10 chickens 1 2 Cluck, cluck! 2 1 2 1 1 2 . .

  2. XEI 506: Solve first-degree inequalities that do not require reversing the inequality sign* XEI 601: Write expressions, equations, and inequalities for common algebra settings Solving Two-Step Linear Inequalities

  3. Two-Step Linear Inequality Now I get it! 2x + 5 >15 – 5 – 5 2x >10 2 2 x > 5 .

  4. Two-Step Linear Inequality Huh??? Can I see that again? -2 + 3x <-11 + 2 + 2 3x <-9 3 3 x < -3

  5. Two-Step Linear Inequality Allan, you don’t get this? This easy! 4x >-8 + 2x – 2x – 2x 2x >-8 2 2 x >-4

  6. Two-Step Linear Inequality 1 4 x + 4 < 2 – 4 – 4 x <-2 x < -8 . . 4 1 1 4 4 1 .

  7. Key Words “At least” means greater than or equal to (>) “No more than” means less than or equal to (<) “More than” means greater than (>) “Less than” means less than (<)

  8. Write Linear Inequalities Tony scored two less than three times the number of points Alonzo scored. If Tony scored more than 13 point, how many could Alonzo have scored? 3a – 2 > 13 3a > 15 a > 5 Alonzo scored more than 5 points.

  9. Write Linear Inequalities Chris has $200 in his bank account. He makes $10 an hour at his job. He wants to save at least $400 to buy some chickens. What is the minimum number of hours Chris will have to work? 200 + 10h > 400 – 200 – 200 10h>200 10 10 h > 20 hours Wants more than this amount! Has already! Mo’ Money, mo’ money, mo’ money!

  10. Write Linear Inequalities Nadia drives a cab. She charges a flat fee of $2 and then $0.50 a mile. How many miles can a customer with no more than $20 travel in Nadia’s cab? $2 + $0.50m < $20 – 2 – 2 0.50m< 18 0.50 0.50 m < 36 miles I charge more than that!
