2-(-3/8)

2+(3/8)

16/8 + 3/8

19/8

4p/6+27=39

4p/6 =12

4p=72

p=18

3% * 55

.03 * 55

$1.65

5200-3140= 2060

2060/5200 = 0.396

0.396 = 39.6% rounds to 40%

|p|/5 +1=0

|p|/5 = -1

|p| = -5

p = 5. (Absolute vales are always positive)

|2x| > 14

|x| > 7

x > 7

Draw a straight dotted line vertically through (7,0) and shade everything to the right of that line

x + 260 + 200 = 480

x + 460 = 480

x = 20
