Inequalities (Day 49)

Bellringer (Day 49) Number Operations Given the following number line, which letter would be the best approximation for ? Algebra 128, 64, 32, 16, _____, _____, ______, ______ Write the next four numbers in the pattern and explain how you got them. Geometry & Measureme nt If two rectangles have the same area, must they have the same perimeter? Prove it. Data/Statisti cs/ Probability Find the median of this data set. 138, 115, 112, 124, 118, 120, 170, 130, 102, 146, 109 Potpourri Tom Terrific has a garden in the shape of a rectangle. He wanted to plant a tree in the exact center of the garden. What would be a way that he could find the center without using any measurement?

Inequalities (Day 49) Bellringer (Day 48) A Number Operations Order the following integers from least to greatest. 5, -13, 78, 0, -34, -3, 14 B Algebra Bill is three years less than twice Jose's age. If Jose is k, what expression represents Bill's age in years? C Geometry & Measurement How many grams are in 2 kilograms? D Data/Statistics/ Probability John writes each letter in the word RHINOCEROS one time on a separate card and puts the card in a bag. Then he draws one card without looking. Find the probability of drawing O? R or S? E Potpourri Conrad’s Taxi Service chargers $1.50 for the first mile and $.90 for each additional mile. How much money will Mr. Kolp owe after traveling 11 miles?

Inequalities (Day 49) Take a stand if... you got tons of candy yesterday. you know what six tenths times two is. you would rather go to a hanted house or work at a haunted house. you know what four hundred times nine is. your favorite football team won on Sunday. you know what one and two-thirds is as an improper fraction.

Inequalities (Day 49) Inequality is a mathematical sentence formed by placing an inequality symbol between two expressions. (Like an equation, but with >,<) Solution of an inequality is a set of numbers you can substitute for a variable to make the statement true y > 75 + g < 20r < or = 0 y = All numbers greater than 4 t = all numbers less than 15 r = all numbers -2 or smaller

Inequalities (Day 49) To solve an inequality… treat it just like an equation and follow your two rules: -Get the variable alone -Balance (do the same to both sides) -NEW…When multiplying or dividing by negative, reverse the inequality

Inequalities (Day 49) -9 + r > r > 21 a - 18 < a <
