Using language to describe meaning The number of Freshmen in a school last year was m, which is 5% higher than last year. What does 5% m mean? (1 + 5%) m mean?

5% m means more people this year than last year
(1 + 5%) m is the number of this year

Solving fractional equation (12 19:29:38)
(1) The 5 of the 5 of the 3 + 3 is the 5 of the 5 = X-1, the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the 3 of the three of the three of the three of the three of the three of the three of the three of the three of the three of the three of the three of the three of the three of the \##\####35\35;#35;\\\\\\\\\\\\\\\\ / 2 + 3 = 2-x 1 / 2-x

First of all, I have a question for you
It's 5 / 2x + 3 = 3 / X-1
Or 2x + 5 / 3 = X-1 / 3
The same can be asked
Question 2

If a is used to represent a person's age and B is used to represent the maximum number of heart beats per minute that a person can bear during normal exercise, then B = 0.8 (220-a)
When a 45 year old person exercises, the number of heart beats in 10 seconds is 22. Is he in danger?

1min=60s
132 times in 1min
b=0.8(220-45)=140
one hundred and thirty-two

The power of rational numbers in grade one mathematics, (the faster the better) (23 19:52:29)
If M and N satisfy the second power of | 3m-6 | + (n + 4) = 0, find the value of the second power of - M.N

Since the second power of | 3m-6 | + (n + 4) = 0 | 3m-6 | and the second power of [n + 4] are opposite numbers, then the front and back should be equal to 0, so the second power of M = - 2 n = - 4 - M is - 2 × - 2 = 4, and the second power of n is - 4 × - 4 = 16
