Answer

x = 17.64

Work Step by Step

$\frac{250}{24.8} = \frac{x}{1.75}$ $24.8x = (250)(1.75)$ $24.8x = 437.5$ $\frac{24.8x}{24.8} = \frac{437.5}{24.8}$ x = 17.64 Check answer $(250)(1.75) = (24.8)(17.64)$ 437.50 = 437.47 Since the value of x was rounded, the cross products are not exactly equal but are close enough to indicate the answer is correct.
