1. Chapter 2 Review Algebra I

2. Use Order of Operations to Solve -2 – (7- 3) ÷ 4 -2 – (4)÷ 4 -2 – 1 = -3

3. Simplify each expression (5x • 3) – 4x + 7 = 15x – 4x + 7 = 11x + 7

4. Evaluate each expression a = 1, b=7, and c = -2 3a + ab – c = 3(1) + 1(7) - -2 = 3 + 7 + 2 = 12

5. Use replacement set to solve C = {10, 11, 12, 13} + 7 = 12 C = {11}

6. Determine whether each pair of ratios forms a proportion. ,, 336≠312 648 = 648 No yes

7. Solve for x. -5 = x + 9 X = -14

8. Solve for x. x + (-4.2) = 8.6 X = 12.8

9. Solve for x. x + (-5) = -2 X = 3

10. Solve for x. X – (-⅝) = ¾ X = ⅛

11. -4a – 1 = -1 -4a = 0 a= 0

12. -2t + 4 = 10 – t -t = 6 t = -6

13. 11 = ½ b – (-3) 8 = ½ b 16 = b b = 16

14. -2( t -2) = 10 – t -2t + 4 = 10 – t -t = 6 t = -6

15. Solve the ratio = 5h = 72 H = 14.4

16. Solve abstractly 7x – c = b Solve for x. 7x = b + c x = b + c 7

17. Write and solve the equation that corresponds to the statement. The sum of y and negative 3 is five. Y + (-3) = 5 Y = 8

18. During one week, Damon made deposits in his checking account of \$532.40 and \$450.98. He wrote a check for \$837.75. By how much did his account increase or decrease during the week? \$532.40 + 450.98 - \$837.75 = \$145.63 increase

19. The sum of two consecutive integers is 125. Find the integers. x + x + 1 = 125 2x + 1 = 125 2x = 124 X = 62 The integers are 62 and 63.

20. Find the principal when the interest is \$300 at 5% rate over 5 years. I = prt 300 = p (5%) (5) 300 = .25 p 1200 = p P = \$1200

21. At the Central Perk coffee shop, Destiny sold 30 more cups of espresso than Cappuccino, for a total of \$163.50 worth of the drinks together. How many cups of each were sold. 2(x + 30) + 2.5x = 163.50 2x + 60 + 2.5x = 163.50 4.5x = 103.50 X = 23 cappuccino and 53 espresso
