The tonnage ratio of the two granaries is 7:5. If 36 tons of grain are transferred from the first granary to the second granary, then the current tonnage ratio of the two granaries is 1:2, and the original tonnage ratio of the two granaries is 1:2
How many tons

84 tons in warehouse A and 60 tons in warehouse B

Solving the equations: (1) 2x-y = 6 (2) (x + 2Y) (2x-y) = 96
Please write the process of solving the problem

The general solution of binary linear equations is to eliminate an unknown number and solve another one first. For example, (1) is changed into y = 2x-6 and substituted into (2) to get (x + 4x-12) (2x-2x + 6) = 96, that is, 5x-12 = 16, x = 28 / 5, and then the value of X is substituted into (1) to get y = 26 / 5. This method can solve most binary linear equations, but

75-25 + 25-75 calculated in a simple way

75-25+25-75
=75+25-(25+75)
=100-100
=0

The sequence {an} is an equal ratio sequence, the number of items is even, and each item is positive. The sum of all items is equal to 4 times of the sum of even items, and the product of the second item and the fourth item is 9 times of the sum of the third item and the fourth item

an=a1*q^(n-1),n=1,2,...,2k.
The sum of all terms is equal to 4 times the sum of even terms, A1 (Q ^ (2k) - 1) / (Q-1) = a1q (Q ^ (2k) - 1) / (Q ^ 2-1)
==> q=1/3.
And A2 * A4 = 9 (A3 + A4) = = > a1q ^ 2 = 9 (1 + Q) = = > A1 = 90
==> an=90*(1/3)^(n-1),n=1,2,...,2k.
Because q = 1 and a (j + 1) = 0 and loga (j + 1)

23+22+21+20…… +1+1+2+3+4+5…… +55

（23+1）*24+（25+55）*（30/2）=1776

For integers a, B, C, D, the symbol ∣ A / D - B / C ∣ denotes the operation AC – BD. given that 1 ∣ 1 / D - B / 4 ∣ 3, what is the value of B + D?
I don't understand. Help me

From | A / D-B / C | = AC - BD
It is known that | 1 / D - B / 4 | = 1 * 4 - BD
That is 1 < 4 - BD < 3
So 1 < BD < 3
Because B and D are integers
So BD = 2
B = 1, d = 2 or D = 1, B = 2
So B + D = 3

The five numbers 12345 make up the four digits without repetition. They are arranged from small to large. What is the number 4125? What is the number 65?

There are four digits that can be made up of: 5 × 4 × 3 × 2 = 120, and each digit in the thousand place has: 120 △ 5 = 24, 41234125. From small to large, 4125 is the second digit of 4 in the thousand place, 4125 is the second digit of all: 24 × 3 + 2 = 74, 65 △ 24 = 2, more than 1724-17 + 1 = 8, the 65th digit of 3 in the thousand place, from large to small

The transpose matrix of a matrix has the same rank as itself

The rank of a matrix is defined as the maximum order of its nonzero subexpressions. Note that the transpose value of the determinant does not change
After transpose, it becomes a sub formula of transpose matrix (transpose of atomic formula). Its value remains unchanged, so it is not a zero sub formula
In other words, the transpose matrix of a matrix has the same rank as itself

If a two digit number is divided by a one digit number, the quotient is still two digits, the remainder is 8, and the sum of divisor, divisor and quotient is______ ．

According to the meaning of the question, the minimum divisor is 8 + 1 = 9, and because the divisor is a one digit number, the divisor must be 9, because it is a two digit number divided by a one digit number, and the quotient is still two digits. If the quotient is 10, then: 10 × 9 + 8 = 98, which is in line with the meaning of the question; if the quotient is 11, then: 11 × 9 + 8 = 107, which is not in line with the meaning of the question; so the divisor is 98, the quotient is 10, the divisor is 9, and the remainder is 8, 98 + 10 + 9 + 8 = 125 The sum of divisor, divisor and quotient is 125
