How many seconds in a day (working out please)

There are 86,400 :D

Step-by-step explanation:

Well, we all know there are 60 seconds in a minute. We also know there are 60 minutes to an hour. So, to find the answer of how many seconds there are in a hour then we times 60 by 60. So:

60 x 60 = 3600

Which, that means there are 3,600 seconds in just a hour. Then, we need to times by 24 because there are 24 hours in one day

So,

3,600 x 24 = 86,400

By the way, good luck on your test!

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.
