Answer:
12 Sections
Step-by-step explanation:
With 138.5 meters needed and fencing being purchased in 12-foot sections, you would need 12 sections purchased. 138.5/12=11.54, this is rounded up to 12 because of the purchase size.

Let h represent Kate's height at birth. Then: 142 cm = 3h - 2 cm.
Combining like terms: 144 cm = 3h, and h = 48 cm.
Kate's height at birth was 48 cm.
If you add a zero at the end it is easier to understand. 0.20 > 0.18 because 20 is greater than 18
When you subtract you are taking away a number but also when you distribute -1 to a number it will take away 1 (because it’s negative) :-) hope this made sense!
