Answer:

$XY = 18$

Step-by-step explanation:

Given

$ABC:AXY = 4 : 3$

$BC = 24$

Required

Find XY

Represent BC and XY as a ratio;

$BC : XY = 24 : xy$

Recall that:

$ABC:AXY = 4 : 3$

Equate both ratios;

$24 : xy = 4 : 3$

Convert to fractions

$\frac{24}{xy} = \frac{4}{3}$

Cross Multiply

$xy * 4 = 24 * 3$

$xy * 4 = 72$

Divide through by 3

$xy * 4/4 = 72/4$

$xy = 18$

Hence:

$XY = 18$
