Hj and jk are the same length line segments ( because the midpoint divides a line into two equal parts)
So hj = jk.
hk is the line segment which has the mid point j. It is the double of hj or jk. It can be the sum of hj and jk.
hj + jk = hk
or
2 * hj = hk
or
2 * jk = hk
Im pretty sure its x less-than-or-equal-to 3
Its already an improper fraction.
If you mean mixed number it would be 7 4/7.
Hope this helps!:)
