Explanation:

The Tang administration or the Tang Empire was a majestic line of China that managed from 618 to 907, with an interregnum somewhere in the range of 690 and 705. It was gone before by the Sui line and followed by the Five Dynasties and Ten Kingdoms period in Chinese history.

The Song administration was a magnificent tradition of China that started in 960 and went on until 1279. The tradition was established by Emperor Taizu of Song following his usurpation of the royal position of the Later Zhou, finishing the Five Dynasties and Ten Kingdoms period.

164 kids

165 adults

step-by-step explanation:

first you need to make two equations

kids = x

adults = y

first equation = x+y=329

second equation = 1.5x + 4y = 906

solve by substitution

x = 329 - y

1.5 (329 - y) + 4 y = 906

493.5 - 1.5y + 4y = 906

combine like terms

2.5y = 412.5

y = 165

plug back into one of the equations

x + 165 = 329

x = 164
