Answer

$x = 153.89$

Work Step by Step

$\frac{4.75}{17} = \frac{43}{x}$ $4.75x = (17)(43)$ $4.75x = 731$ $\frac{4.75x}{4.75} = \frac{731}{4.75}$ $x = 153.89$ Check answer. $\frac{4.75}{17} = \frac{43}{153.89}$ $(4.75)(153.89) = (17)(43)$ $730.98 = 731$ The products are slightly different due to rounding but are close enough to indicate a correct result.
