Answer:

she slept for 3 hours

Step-by-step explanation:

its actually simple so we know that April slept for 9 hours bug Evelyn only slept 2/3 of 9 hours and if you add 1/3 and 2/3 you get 3/3 which equals a whole so all you have to do is devide 9 into 3 and you get 3 parts with 3 now you add 3 and 3 together and that equals 6 and that was two parts you added which is equaled to 2/3 so all you have to do now is subtract 9-6 and you leave with three which is 1/3 so we come to the final answer she slept for three hours

Given the formula D = ABC what is the formula for C

Andru [333]

In order to solve for C, you need to get it by itself. You would do this by dividing both sides by A and B. if you do this you get C=D/AB. Therefore, your answer would be D

The best way to solve this problem is by plugging in each answer choice for both equations and seeing which one works. You can already see that choice A doesn't work because -1 is not greater than or equal to 4. That means you just need to test choices B and C!

Choice B (4, -2)
$x + y \geq 6\\
4 + -2 \geq 6\\
2 \geq 6 
$
2 is not greater than or equal to 6, so choice B doesn't work.

Choice C (4, 2)
$x + y \geq 6\\ 
4 + 2 \geq 6\\ 
6 \geq 6 \\\\
x \geq 4\\
4 \geq 4$
Since 6 is equal to 6 and 4 is equal to 4, choice C works!

What is the elapsed time from 6:45 am to 3:28 pm

Genrish500 [490]

6:45a to 7:45 = 1 hour

7:45 to 8:45 = 2 hours

8:45 to 9:45 = 3 hours

9:45 to 10:45 = 4 hours

10:45 to 11:45 = 5 hours

11:45 to 12:45 = 6 hours

12:45 to 1:45 = 7 hours

1:45 to 2:45 = 8 hours

2:45 to 3:00 = 8 hours and 15 minutes

then just add the 28 minutes to the 15 minutes

28 + 15 = 43

6:45a to 3:28p = 8 hours and 43 minutes.

Hope this helps.
