HJ is 4.0 and JE is 4.
Here's a detailed explanation: It's mentioned that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem, the line segment that connects the midpoints of two sides is parallel to the third side and is half its length. As JH connects these midpoints,
HJ = 1/2 (GF) and therefore the calculations show that HJ equals 8 and JE equals 4.
1) In 2000, magazine A had 5,000 subscribers more than magazine B. 2) The available options indicate that the subscription numbers for both magazines are dropping. 3) As the years progress from 2000, the subscriber counts for both magazines approach zero.
Solution:
Given that
G being the midpoint of FH implies

Additionally, we have

Hence, we can express

Therefore, 
When rounding 243.875: to the nearest tenth, it becomes 243.9; to the nearest hundredth, it is 243.88; to the nearest ten, it rounds down to 240; and to the nearest hundred, it rounds down to 200. The general rule in rounding states that if the decimal is less than 5, the number remains the same; if it is 5 or more, you round up.
