Vera is using her phone .its battery life is down to 2/5 and it drains another 1/9 every hour . how many hours will her battery last?

Step-by-step explanation:

To solve this you have to find like terms for the fractions:

2/5 => 18/45 (amount of power remaining)

1/9 ==> 5/45 (power consumption per hour)

If we divide 18 by 5 (the amount of power we have left divided by the amount of power consumption we use per hours), we find that the battery will last 3.6 more hours.

I hope this helps!

i dont know it

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
