Harman [31]

Answer:

You could drive 2805 miles on 55 gallons of gas

The car's gas mileage is 51 miles per gallon

Step-by-step explanation:

First, find the gas mileage by dividing the given number of miles by the number of gallons:

510/10

= 51

The car's gas mileage is 51 miles.

Find how far you can drive on 55 gallons of gas by multiplying 51 by 55

51(55)

= 2805

So, you can drive 2805 miles.

What is the difference?

babymother [125]

Answer:

$\dfrac{x^2+3x-12}{(x+3)(x-5)(x+7)}$

Step-by-step explanation:

Factor the denominators, then use a common denominator to add the terms.

$\dfrac{x}{x^2-2x-15} -\dfrac{4}{x^2+2x-35} =\dfrac{x(x+7)}{(x+3)(x-5)(x+7)}-\dfrac{4(x+3)}{(x+3)(x-5)(x+7)}\\\\=\dfrac{x^2+7x-4x-12}{(x+3)(x-5)(x+7)}=\boxed{\dfrac{x^2+3x-12}{(x+3)(x-5)(x+7)}}$
