1. convert feet to inches 24 inches 2 feet = 40 inches 5 simplify ÷ 8 24 inches 3

2. 32 min. 8 ÷ 4 = or 8: 9 36 min 9

3. \$51.00 -\$8.00 Wednesday \$51.00-\$8.00 = \$43. 00

6. \$2.42 = . 2857... \$. 29 per unit price ounce 8.4

7. 6.20 3.95 = . 31 = . 26 15 20 2.20 3.20 = = . 44 . 32 5 10

8. 344 miles 31.27 = 11 hours

9. 62.6 gallons = 6.3 6.26 = 10 months

10. 5,349 words 5,349 89.15 = 1 hour = 60 minutes 60 round 89.2

11. convert hours to seconds = 240 times 60 4 times 60 = 14400 seconds 255 times 1000 = meters 255000 = 18 17.708... = 14400

12. notice that the mixture requires twice as much water as weed Killer. half of 3 is 1. 5

13. games won X 3 = 4 60 games played = 180 4 × X = 45 4 4

14. 177 Earth 2,036 = x Space Station 34 69,224 = 177 × 391 X = 177 177

15. two-step equation 8 32 = 2 x+6 x+3 = -6 -6 4 2 one-step equation 26 = 2 × × = 13 2 (X+3) 32 = 2 2 distributive property

16. NOT zigzag q q = = 12 18 12 = 12 = 6 6 yes no yes yes

17. zigzag 9 3 12 4 = 36 36

18. x 8 1.777... = q 2 = 1.78 = 9X 16 9 9

19. model 10 feet long 7 feet wide = real village 7 miles long X 1OX = 49 x = 4.9 10 10

20. compare corresponding sides 30 75 30 = X = zigzag 12 x one-step equation x = 30 900

21. compare corresponding sides then solve one-step equations use two proportions -then zigzag- y 12 12 21 = and = x 4 4 6 y = 4 y = 18 = X = 72 7 12 × 84

22. set up a proportion to solve zigzag 70 X 1400=50 × 50 20 X=28

23. only answer with center A

24. dashed is bigger therefore an enlargement 2 times 3 makes 6 count

25. set up ratio 5cm 1cm ÷ 5 scale factor <1 20cm 4cm reduce

26. means enlargement 2 scale factor > 1 6 2 times 3=6 x X

27. ! Draw a picture to help solve Set up a proportion comparing corresponding sides zigzag 4m X 4 100 x 8 100 m 8m 8 x=400 Building Pole Shadow Shadow X=50 m

28. ! draw a picture to help solve sides set up a proportion and compare corresponding zigzag 47 70 70in X X 33 47 × = 2,310 33in 47in X = 49

29. compare corresponding sides in a proportion zigzag 27 × X 12 4 108 12 × = X=9 27 AD = 12+15 =

30. set up a proportion to compare corresponding sides X zigzag x 44 X=18.33 = 12 × = 220 12 5
