Question

According to​ statistics, a person will devote 33 years to sleeping and watching tv. the number of years sleeping will exceed the number of years watching tv by 19. over the​ lifetime, how many years will the person spend on each of these​ activities?

Answer 1

Let n represent the number of years watching TV.

Then let sleeping represent as n+19.

Solution for this problem is:

n+n+19=33

2n=14

n = 14 divided by 2

n=7

7 years are spent watching TV while 26 years are spent in sleeping.

 

Other solution:

To figure out how many years you spend sleeping and watching TV, you first need to take the number in total, which is 33, and subtract the number that you will exceed sleeping.33 – 19 = 14. Now that you have the number 14, you can see that 14 divided in 2 = 7. 7 +19 = 26. This leaves you with a remainder of 7 hours watching TV and 26 hours sleeping. 26 is 19 greater than 7. 7 + 26 = 33.

Answer 2

Based on the total number of years to be spent on sleeping and watching tv, the number of years for each of these is:

• Sleeping - 7 years .
• Watching TV - 19 years.

What is the amount of time spent on watching TV?

To find the number of years spent watching television, the formula is:

Total number of years for watching tv and sleeping = Number of years watching tv + Number of years sleeping

Assume the amount of time spent watching TV is x, the relevant expression would be:

33 = x + (x + 19)

33 = 2x + 19

2x = 33 - 19

x = 14 / 2

= 7 years

Amount of time spent sleeping

Sleeping is 19 years more than watching tv:

= 7 + 19

= 26 years
