Apainter takes 2 3/5 hours to paint a wall. how many hours will the painter take to paint 8 walls if she works at the same rate?

 hours

Step-by-step explanation:

If 1 wall takes    hours to paint,

8 walls would take    hours to paint [given same rate].

Changing    into improper fraction [for ease of multiplying]:

Now multiplying    with 8 gives us:

 hours

In decimal it is  hours

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
