Always, Sometimes, Never 1 - 100 3-100A Sometimes 3-200 When multiplying a positive and negative number together, the answer is __________ negative Always, Sometimes, Never 1 - 100 3-200A Always 3-300 This property says that a + -a = 0 1 - 100 3-300A Property of Opposites or Additive Inverse Property 3-400 The expression -11 – (-14) can be written as this addition problem. 1 - 100 3-400A -11 + 14 3-500 Evaluate 3 – 2(6 – 12) + 4(1 – 3)28 1 - 100 3-500A 17 1 - 100 4-100 Terms that have the same variables raised to the same exponents are called this. 1 - 100 4-100A Like Terms 4-200 This property can be used to help rewrite the expression 3(3x - 4y) 1 - 100 4-200A Distributive Property 4-300 These are the two steps required to simplify an expression like: 3(2x – 5) + 4(7 – 5x) 1 - 100 4-300A 1. Distribute 2. Combine Like Terms 4-400 Simplify the following expression: -3(4x - 2) - 4(6 - 5x) + 4 1 - 100 4-400A 8x - 14 4-500 Simplify the following expression: 32 x 16 6 (5 x 3) 4(2 x 5) 8 1 - 100 4-500A 7x - 19 1 - 100 5-100 “Sum”, “More Than”, “Greater Than”, “Plus” are these 1 - 100 5-100A Words that mean add. 5-200 This is a letter that represents a number. 1 - 100 5-200A Variable These are the two variables that should be defined in the following situation: 5-300 The number of tomatoes in John’s garden is five more than twice the number of carrots. 5-300A 1 - 100 T= # of tomatoes C = # of carrots 5-400 Translate the following into algebraic symbols: Five more than the product of six and a number is at least twenty. 1 - 100 5-400A 6x + 5 20 5-500 Translate the following into symbols: The number of points scored by the Packers is one less than twice the number scored by their opponents. 1 - 100 5-500A P = 2T - 1 1 - 100 6-100 When faced with a word problem, the first thing that I should do is ths. 1 - 100 6-100A Define a variable 6-200 Addition ________ comes before Always, Sometimes, Never subtracion. 1 - 100 6-200A Sometimes 6-300 Evaluate if x = 2 and y = -4: 3(x – y) + 2xy – (x + y)2 1 - 100 6-300A -2 6-400 I need to have a common denominator when doing these operations with fractions. 1 - 100 6-400A Addition and Subtraction 6-500 Simplify the expression: 10 x 4 y 24 x 12 y 3(3x 5 y ) 2 6 1 - 100 6-500A 15y Write the following in words: 2(x + 5) = 7 – 3x Two times the quantity five more than a number is the same as seven decreased by three times a number.
