Mary drove 303 miles in 15 gallons of gas at this rate how many miles would she drive using 16 gallons of gas

1 answer:

4 0

324 because if you do 303/15 it’s 20.2 then you add that to 303 which is 323.2 but you can’t have .2 of a gallon so it’s 324

Answer:

Hi,

Step-by-step explanation:

We can't solve that but reduce it to the same denominator.

$\dfrac{x+5}{x}+\dfrac{x+8}{x-1}\\\\=\dfrac{(x+5)(x-1)+x(x+8)}{x(x-1)}\\\\=\dfrac{x^2+5x-x-5+x^2+8x}{x(x-1)}\\\\=\dfrac{2x^2+12x-5}{x(x-1)}\\$
