A person deposits 2000 yuan into the bank on a fixed term basis, withdraws 1000 yuan for shopping after maturity, and the remaining 1000 yuan and the interest due are all fixed on a fixed term basis For example, in a bank, if the deposit interest rate in the second year is 2% lower than that in the first year, and the principal and interest after maturity are 1296 yuan, the annual interest rate of fixed deposit in the first year is ()

[2000 * (1 + x) - 1000] * [1 + (x * 100-2) / 100] = 1296, x = 10%. It's a test. I haven't solved the equation for a long time. It took more than an hour to work out 10%
In the first year, the principal and interest totaled 2200, the withdrawal was 1000, and the remaining 1200. The interest decreased by 2 percentage points to 8%, and the 1200 * 8% was 96 yuan plus the principal was 1296 yuan

A person deposits 2000 yuan into the bank on a one-year basis, withdraws 1000 yuan for shopping after maturity, and deposits the remaining 1000 yuan and the interest due to him in the bank on a one-year basis. If the interest rate of the deposit remains unchanged, he will get 1320 yuan of principal and interest after maturity, and calculate the annual interest rate of this deposit method

Let the annual interest rate of this kind of deposit be X. from the meaning of the question, we can get [2000 (1 + x) - 1000] (1 + x) = 1320, and the solution is: X1 = - 1.6 (not conforming to the meaning of the question, rounding off), x2 = 0.1, and the annual interest rate of this kind of deposit is: 0.1 = 10%

X - 5 / 2 times x = 18 / 25
I can't grade equations

X - 5 / 2 times x = 18 / 25
-3x/2=18/25
x=-12/25

-18-25=?

-43

How do you do one in 10 minus one in 100 plus one in 1000?

The denominator of 1 / 10, 1 / 100 and 1 / 1000 is divided into 1000, and the numerator is multiplied by 100; 10; 1. It becomes 100 / 1000, 10 / 1000 and 1 / 1000. That is 100 / 1000 minus 10 / 1000 plus 1 / 1000. Then the numerator is added to 100-1 + 1 = 91

What's the value of △ 100 × 1000 △ 10 = 5

Let the size of? Be X
So, yes
x÷100×1000÷10=5
That is, X × (1000 / 100 / 10) = 5
That is, X × 1 = 5
So x = 5
It's five
