If someone sleeps 8 hours a day for 75 years how many hours did that person sleep in his lifetime?
ra1l [238]
The person sleeps 8 hours a day.

There are 365 days in a year and 366 days in a leap year.

A leap year occurs every 4 years.

If we divide 75 by 4, we get 18.75. This number represents how many leap years occurred in 75 years. So, the person experienced approximately 19 leap years.

19 leap years has 6954 days.

The other 56 years, which have 365 days each year, have a total of 20,440 days.

That's a total of 27,394 days.

27,394 × 8 = 219,152 hours

This is approximately 24 years or 9,131 days.

Read the question on the picture.
Marizza181 [45]

These two lines are congruent (the same) so we can set them equal to each other and solve.

5x-4=3x+6

The first thing we need to do is subtract 3x from both sides leaving us with 2x-4=6

Now we can add 4 to both sides leaving us with 2x=2

Now we need to divide both sides by 2 to get x alone.

Giving us our final answer of x=1

What is the sum of 2/5 and 2/4?
mihalych1998 [28]
A/b+c/b=(a+c)/b
make bottom number same

multiply by 1 or x/x where x=x
easy way is
if you had
a/b+c/d
multiply a/b by d/d and multiply c/d by b/b

2/5 times 4/4=8/20
2/4 times 5/5=10/20

add

8/20+10/20=(8+10)/20)=18/20=9/10

I should have simplified 2/4 to 1/2 first
