Thes first rule is correct. 

Another way of doing it is:

Sum the digits of the number. If the result is divisible into nine, then the original number itself will also be.

Example:

18 = 1+8 = 9. 9 is divisible into 9.

27 = 2+7 = 9. 9 is divisible into 9.

Wish you luck!

We can see that the 33 degrees corresponds to angle A (parallel lines) meaning they’re equal.
This means that 33 + 2x = 5x (5x is the exterior angle, so the other two interior angles’ sum must equal to it)
3x = 33
x = 11

April, x, slept 9 hours; Evelyn slept 2/3
xeze [42]

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

sorry for such a long explanation
