Math Problem Statement

Given a line segment JL with total length 15x + 110, segment JK as 6x + 51, and segment KL as 2x + 24, solve for x.

Solution

The image shows a line segment JLJL with points JJ, KK, and LL marked on it. The total length of segment JLJL is represented by the expression 15x+11015x + 110. The segment from JJ to KK is given by 6x+516x + 51, and the segment from KK to LL is represented by 2x+242x + 24.

We need to find the value of xx by setting up the equation that represents the entire line segment JLJL as the sum of its parts JKJK and KLKL:

JK+KL=JLJK + KL = JL

Substitute the expressions for JKJK, KLKL, and JLJL:

(6x+51)+(2x+24)=15x+110(6x + 51) + (2x + 24) = 15x + 110

Let's solve this equation for xx.The solution to the equation is x=5x = -5.

Now that we have the value of xx, we can find the lengths of segments JKJK and KLKL by substituting x=5x = -5 into the expressions for each segment:

JK=6x+51,KL=2x+24JK = 6x + 51, \quad KL = 2x + 24

Would you like to proceed with calculating these lengths or have any other questions?

Here are some questions you might consider next:

  1. What are the lengths of the segments JKJK and KLKL with x=5x = -5?
  2. How do we verify that the total length JLJL equals the sum of JKJK and KLKL?
  3. What would happen if the expressions for segments were different?
  4. How can negative values for xx affect the lengths of geometric figures?
  5. Can we interpret this problem in a real-world context?

Tip: When solving equations involving geometry, always check if the value makes sense in the context of the problem.
