6 0

Step-by-step explanation:

\frac{2}{3} (a - 9) -  \frac{1}{6} ( - 2a  + 18)

=  \frac{2a - 18}{3}  -  \frac{2a - 18}{6} \\  =  \frac{2a - 18 - (6a - 54)} 6

=  \frac{2a - 18 - 6a + 54}{6}\\=  \frac{ - 4a + 36}{6}  \\   = \frac{4( - a + 9)}{6}  \\  =  \frac{2( - a + 9)}{3}

There are other species of elephants, namely the Asian and the Indian, but they are much smaller than the African. The African elephant is the king among the giants on land. No other land animal comes close to the size of these creatures. It would take 165 full-grown men to make up the same weight as the world's record African elephant. The noise of an elephant digesting its food (when its tummy's growling) can be heard up to 600ft/183m away. Elephants actually have control over their digestive processes because they are able to stop the sounds of digestion when they sense danger. Here are some other cool elephant factoids:
