A. 11.25

Step-by-step explanation:

If point C(x, y) divides line segment AB with end points at A( x_1,y_1 ) and B( $x_2,y_2\\$ ) in the ratio on n:m, then the coordinates of point C is:

$x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1$

Given that segment AB is divided by point C in the ratio of 3:1. Given A(3, 12) and B (14, 17). Let coordinate of C be (x, y), hence:

$x=\frac{n}{n+m}(x_2-x_1)+x_1\\\\x=\frac{3}{3+1}(14-3)+3=\frac{3}{4}(11)+3=11.25 \\\\\\y=\frac{n}{n+m}(y_2-y_1)+y_1\\\\y=\frac{3}{3+1}(17-12)+12=\frac{3}{4}(5)+12=15.75$

Therefore, the coordinate of point C = (11.25, 15.75)

The x coordinate of point C is 11.25
