J is between H and K. HJ = 2x + 5 JK = 3x - 7 KH = 18 Find JK.
- A 5
- B 8
- C 7
- D 4
That's Correct!
It's Wrong!
Since J is between H and K, we can determine the value of x by setting the distances between J and H and J and K equal to each other.
Therefore, 2x + 5 = 18 - (3x - 7).
Simplifying the equation gives us 5x = 20, which means x = 4.
Substituting x = 4 into JK = 3x - 7 gives us JK = 3(4) - 7 = 12 - 7 = 5.
Therefore, the correct answer is 5.
