Answer: x=4

Steps: (I am assuming your question has a typo in it and by "c" you meant "x")

The rational expression equals zero

$\frac{x-4}{x-6}=0$

only when the numerator equals 0 (the denominator cannot ever be zero):

$x-4 = 0 \\x = 4$

and that happens only for x=4

A car is traveling at a steady speed. It travels 2 1/2

Ksivusya [100]

Answer:

It will travel

$33 \frac{1}{4} \: miles$

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

$\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes} = \frac{x}{45 \: minutes} \\ \\ \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} } = \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} } \\ \\ x = 33\frac{3}{4}$
