Solving and graphing one-Step Inequalities

Sort each inequality into the correct process. FLIP THE SIGN multiply by a negative number divide by a negative number DON'T FLIP THE SIGN multiply by a positive number divide by a positive number add a positive number subtract a positive number subtract a negative number Choose the correct solution. The BLUE part is the solution! A B C D A B C D Match the list of possible answers to the inequality. x + 3 ≤ 8 - 2, 0, 5 ... x + 3 > 8 6, 9, 15 ... x + 3 A B C D A B C D Match the word problem to the inequality. A. The water level in the aquarium’s shark tank is always greater than 250 feet. If the water level decreased by 6 feet during cleaning, what was the water level before the cleaners took out any water? x - 6 > 250 B. Danny has $15 more than his big brother. Danny’s big brother has at least $250. How much money does Danny have? x + 15 ≥ 250 C. Alicia earns $6.00 per hour working at a part-time job. She wants to earn more than $250 this week. How many hours does Alicia have to work? 6x > 250 D. Hank needs to save at least $250 to ride the bus to his grandparent’s home. If he saves $15 a week, what is the least number of weeks he needs to save? 15x ≥ 250 -2x > 18 x > -9 x < -9 x > 9 x < 9 n ≤ - 20 n ≤ 20 n ≥ - 20 n ≥ 20 Solve and graph the inequality given.
