Answer:

The value of x is 2.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denorminator the same :

\frac{x}{x - 2}  +  \frac{1}{5}

=  \frac{5x}{5(x - 2)}  +  \frac{x - 2}{5(x - 2)}

=  \frac{5x + x - 2}{5(x - 2)}

=  \frac{6x - 2}{5(x - 2)}

Then you have to do cross multiplication :

\frac{6x - 2}{5(x - 2)}  =  \frac{2}{x - 2}

(6x - 2)(x - 2) = 5(2)(x - 2)

6 {x}^{2}  - 12x - 2x + 4 = 10x - 20

6 {x}^{2}  - 14x + 4 = 10x - 20

6 {x}^{2}  - 14x + 4 - 10x + 20 = 0

6 {x}^{2}  - 24x + 24 = 0

6( {x}^{2}  - 4x + 4) = 0

{x}^{2} - 4x + 4 = 0

{x}^{2} - 2x - 2x + 4 = 0

x(x - 2) - 2(x - 2) = 0

(x - 2)(x - 2) = 0

x = 2

If a car is traveling 92 feet per second, how many miles per minute is it traveling?
Jobisdone [24]
It’s A because 92 times 60 is 5520 divide that by the conversion of miles to a foot which is 5280 so 5520 divided by 5280 equals 1.045 or 1.05
