### Answer Key

**1. D
**7X is greater than 5X for any value of a positive X. However, if the number was negative, 7x would be smaller.

**2. C
**3X + 3 = 15

X=4

A – 20 – 4 = 16

B – 4 * $ = 16

**3. D
**The relationship cannot be determined. A will be greater or lesser than B depending on the values chosen.

**4. A
**7x – 9 = 47

X = 8

So 5X > 4X + 2

**5. B
**The average = (5 + 9 + 12 + 15)/4 = 10.25 < 10.5

**6. A
**25% of 60 = 15

19% of 45 = 8.55

**7. A
**2,199 + 5,832 = 8.031

3,406 – 2,767 = 639

**8. B
**6.75 / 3.2 = 2.109

4.2 / 1.4 = 3

**9. C
**7(2y + 8) = 168

Y = 8

2Y + 3 = 19

3Y -5 = 19

**10. B
**2/5 + ¾ = 4/20 + 15/20 = 19/20

6/9 + 5/6 = 24/36 + 30/36 = 54/36
