A car traveld 32 miles in 4 hours at this rate how many miles will the car travel in 0.5 hours
Mandarinka [93]

Answer:

4 miles

Step-by-step explanation:

In order to find how many miles the car will travel in 0.5 hours, we can set up a proportion.

\frac{32}{4} = \frac{x}{0.5}

We can now cross multiply to find the value of x.

32 \cdot 0.5 = 16\\\\16\div4 = 4

So the car can travel 4 miles in 0.5 hours.

Hope this helped!

4/x-1+6/x+1=-12/x^2-1
Mademuasel [1]
\frac{4}{x - 1} + \frac{6}{x + 1} = \frac{-12}{x^{2} - 1}

\frac{4(x + 1)}{(x - 1)(x + 1)} + \frac{6(x - 1)}{(x - 1)(x + 1)} = \frac{-12}{x^{2} - 1}

\frac{4x + 4}{x^{2} - 1} + \frac{6x - 6}{x^{2} - 1} = \frac{-12}{x^{2} - 1}

\frac{10x - 2}{x^{2} - 1} = \frac{-12}{x^{2} - 1}

(10x - 2)(x^{2} - 1) = -12(x^{2} - 1)
10x^{3} - 10x^{2} - 2x^{2} + 2 = -12(x^{2}) + 12(1)
10x^{3} - 12x^{2} + 2 = -12x^{2} + 12
10x^{3} - 12x^{2} + 12x^{2} + 2 = -12x^{2} + 12x^{2} + 12
10x^{3} + 2 - 2 = 12 - 2
\frac{10x^{3}}{10} = \frac{10}{10}

x^{3} = 1
x = 1
