Answer:
c. Include the date on each page of notes
Step-by-step explanation:
The main reason for her not being able to do this is because she did not include the date on each page of notes. Failing to do so means that she does not know which notes she took first and which ones she took later, therefore preventing her from correctly organizing the notes based on when they were taken (in the correct order). Neither the class title or the names of the guest speaker prevent her from organizing her notes in order, thus making the answer c.

Answer:
2x + 45 = 6
Step-by-step explanation:
(2/9)x + 5 = 2/3 Subtract 5 from both sides
(2/9)x +5-5=2/3-5
(2/9)x = - 4 1/3 Multiply by 9
2x = -13/3 * 9
2x = -39
x = -19.5
==============
I see. You don't want it solved. Multiply by 9 to clear the fractions.
==============
2x + 45 = 6
==============
Solve it now. It should be easier.
2x = 6 - 45
2x = - 39
x = -19.5
Sin (2 pi/3) = sqrt(3)/2
you can get this from the unit circle
