If 6x △ 4.5 = 8, then 7x-______ =29.5．

6X △ 4.5 = 8 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 6x = 4.5 × 8 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; x = 67 × 6-29.5 = 42-29.5 = 12.5, so the answer is: 12.5

On March 10, 2011, a 5.8 magnitude earthquake occurred in Yingjiang County, Yunnan Province
On March 10, 2011, a 5.8 magnitude earthquake occurred in Yingjiang County, Yunnan Province. After learning the news, teachers and students of a school in our city actively donated money for disaster relief. It is known that 30 students in class 1, Grade 7 of the school donated 360 yuan in this activity
If Xiao Ming makes statistics on the donations of the whole class, he will get the following table:
Donation (yuan)
Number of people (person)
But the number of people who donate 5 yuan, 8 yuan and 10 yuan is covered by ink. Can you work out the number of people who donate 5 yuan, 8 yuan and 10 yuan according to the information provided?
It's due tomorrow,

15 * 16 = 240 yuan
360-240 = 120 yuan
30-16 = 14
5. 8, 10 the total amount of donation is 120 yuan, because 120 can be divided by 5, 10, so consider the multiple of 8 40, 80, greater than or equal to 120 should be removed
If the number of people who donate 8 yuan is 5, there are still 9 people left. We can regard the number of people who donate 5 yuan as X, and the number of people who donate 10 yuan as 9-x. thus we can get the equation 5x + 10 (9-x) = 120-40, x = 2
If the number of people who donate 8 yuan is 10, and there are still 4 people left, we can regard the number of people who donate 5 yuan as X, and the number of people who donate 10 yuan as 4-x. thus we can get the equation 5x + 10 (4-x) = 120-40, x = - 8, and the number of people can not be calculated as a negative number,
So: donation (yuan) 581015
Number (person) 25716
Hope to help you!
