The height(zipper) would be 3 feet or 36 inches
Cirrus clouds form at a height of more than 6000 meters above the earth. This means the inequality should represent the height more than 6000. The correct inequality for this case will be:

This inequality shows that h which is height where Cirrus clouds are formed is greater than 6000m.
Answer:
8 and 15/16 or 143/16
Step-by-step explanation:
3.25 * 5.5 = 17.875/2
Solve :
1/2(x + 32) = -10....multiply both sides by 2
x + 32 = -10 * 2
x + 32 = -20
x = -20 - 32
x = - 52 <===
check :
1/2(x + 32) = -10.....when x = -52
1/2(-52 + 32) = -10
1/2(-20) = -10
-20/2 = -10
-10 = -10 (correct)
