Answer:
10
Explanation:
The coordinate of point X such that MX:XJ=1:1 is the midpoint of MJ.
This is as a result of the fact that it divides MJ into equal ratios.
• The coordinate of M=2
,
• The coordinate of J=18.
[tex]\begin{gathered} \text{Midpoint}=\frac{2+18}{2} \\ =\frac{20}{2} \\ =10 \end{gathered}[/tex]
The coordinate of X is 10.
