Final answer:

To find the values of HJ and JK, we solve the equation (5x - 3) + (8x - 9) = 13 for x, and then substitute this value back into the expressions for HJ and JK to obtain their lengths.

Step-by-step explanation:

To solve the problem, we need to find the values of HJ and JK given that JK = 8x - 9, HJ = 5x - 3, and KH = 13. Given the segments are parts of a continuous line, we can deduce that HJ + JK = KH. Substituting the expressions for HJ and JK into the equation, we can solve for x:

  1. Write the equation for the continuous line: (5x - 3) + (8x - 9) = 13.
  2. Simplify the equation: 13x - 12 = 13.
  3. Add 12 to both sides: 13x = 25.
  4. Divide both sides by 13: x = 25 / 13.
  5. Substitute x back into the expressions for HJ and JK:
  • HJ = 5x - 3 = 5(25/13) - 3,
  • JK = 8x - 9 = 8(25/13) - 9.
Simplify the expressions to find the lengths of HJ and JK.

The correct answer is HJ and JK, given by the above expressions after simplifying.
