Chapter 1 and 2 REVIEW Simplify: 5y – (2y – 8) 3y + 8 Is 4 a solution of 6d – 7 > 17? Explain your answer using 2 complete sentences! No, 4 is not a solution. When I substituted 4 in for d, the expression simplified into 17 > 17, which is not true. 17 is equal to 17, not greater than. Evaluate the expression: 19 – 4x + x3 when x = 3. 34 Write a variable expression for 6 times the sum of k and 3. 6(k + 3) Name all the number sets to which the numbers belong. (whole number, an integer, or a rational number.) 8 1/6 0 -99 7.28475 8 1/6 Rational 0 Rational, Integer, Whole # -99 Rational, Integer 7.28475… Irrational Write a variable expression for “16 less than a number, m, cubed. 3 m - 16 Find the change in temperature from 10*F to -16*F. 26*F Simplify: 7(r + 1) + 3(r + 1) 10r + 10 Find the Product: (9)(-2)(3)(-1) 54 What is the multiplicative inverse of -19? - 1/ 19 Simplify the expression: 20h – 4 4 5h - 1 Find the quotient: 8 ÷ (- 2/ ) 5 -20 Find the quotient: 8 ÷ (- 4 2/ ) 7 - 28/ 15 Tell whether the number is rational or irrational. Give a reason for your answer. √7 √25 √7 Irrational. 7 is not a perfect square so the decimal will continue forever. √25 5. Rational. 25 is a perfect square. Identify the terms, like terms, coefficients, and constant terms. THEN, simplify the expression. 8c – 8 + 5 – 9c + 2 2c 8c – 8 + 5 – 9c + 2c2 • Terms: 8c, -8, 5, -9c, 2c2 • Like terms: 8c, -9c AND -8, 5 • Coefficients: 8, 2, and -9 • Constant terms: -8 and 5 • Simplified Answer: 2 2c -1c – 3 Simplify: - 3/ 8 ÷ 3/ 10 - 5/ 4 Simplify: (5)(-5)(2) -50 Estimate 29 29 Is between 25 and 36 Since 25 is closer to 29, The 29 is ≈ 5. Simplify: -8(p – 3) -8p + 24 Simplify: 7 5x + 7 14x 7 19x
