segment addition / subtraction (numbers)

Explanation:

Step1: Recall segment - addition postulate

If a point $K$ lies on a line - segment $\overline{JL}$, then $JL=JK + KL$.

Step2: Substitute given values

We are given that $JK = 7$ and $KL = 5$. Substituting these values into the formula $JL=JK + KL$, we get $JL=7 + 5$.

Step3: Calculate the length of $JL$

$JL=12$.

Answer:

$12$
