Answer:
8 inches.
Explanation:
We have been given that point K is between points M and Q.
Line segment MK = 7 inches
Line segment MQ = 15 inches.
To find the length of segment KQ we will subtract length of segment MK from length of line segment MQ as total length of a line segment equals to the sum of lengths of its parts.
![\text{Length of segment MQ}=\text{Length of segment MK+Length of segment KQ}](https://img.qammunity.org/2019/formulas/mathematics/high-school/ay43yy7dbt026plrhakhgnr46porjllyhi.png)
![\text{Length of segment KQ}=\text{Length of segment MQ-Length of segment MK}](https://img.qammunity.org/2019/formulas/mathematics/high-school/9scnes2f1pdm8hp0rtxrx1za5js598m87c.png)
![\text{Length of segment KQ}=\text{15 inches -7 inches}](https://img.qammunity.org/2019/formulas/mathematics/high-school/amfjihyvifvurmh217hffhy7lfvt7qjdr4.png)
![\text{Length of segment KQ}=\text{8 inches}](https://img.qammunity.org/2019/formulas/mathematics/high-school/ayif1p3ym88adn47ui4nvgm7jn7sdr3x7i.png)
Therefore, the length of line segment KQ is 8 inches.
