Vera is using her phone its battery life is down to two fifths and it drains another one nineth fraction every hour. how many hours will her battery last

3.6

Step-by-step explanation:

ok, Where x= total hours, the function is (2/5)-(1/9)x=total life

5ths and 9ths dont get along, so we must find a common denominator, in this case 45.

so now we have 18/45-5/45x=TL

or .4-.111...x=tl

By  plugging in numbers, I got 3.6 hours of life
