John’s heart beat at a rate of 65 beats a minute when he is awake and 50 beats a minute when he sleeps (8 hours). How many times

Anarel [89]

His heart beats 86,400 times within a 24 hour period.
60 minutes in 1 hour, so you would multiply 8 hours by 60 mins, giving you 480 mins. 24 hours- 8 (time he's asleep) will give you 16. 16 * 60 will give you 960 minutes. 480 minutes (when he's asleep) * 50 beats a minute = 24,000.
960 (when he's awake) * 65 beats a minute = 62,400. add 24,000 and 62,400 = 82,400 beats in 24 hours.

When 13 is subtracted from the sum of 2 consecutive numbers the answer is 18 what are the consecutive numbers?

Hitman42 [59]

Let x = the first number
x+1 = the second number

The sum of our two numbers is therefore: x + (x+1)

When you subtract 13 from the above you get 18 left over.

So our equation is:

x + (x+1) - 13 = 18

Now we can just solve for x:

x + (x+1) = 31

2x + 1 = 31

2x = 30

x = 15

So our first number is 15 and our second number must be 16.
