The first installment will be paid at the time of purchase, and the second installment will be paid one year later. The full price and the interest of the part owed after the first installment will be paid. If the annual interest rate is 4.5%, how many yuan should be paid in each installment?

Set X Yuan for each payment
(10225-X)×4.5% +(10225-X)=X
X=5225

I just want to ask you: there are x benches in an auditorium. Today, there are several people in the auditorium. One of the benches has only two seats, six of them are vacant, and the others have five seats. Try to express the number of people with X and find the algebra when x is equal to 70.

In the column of - 49, - 48, - 47..., 2004, what is the sum of the first 99 consecutive integers? What is the sum of the first 100 consecutive integers?

Analysis,
The first 99 consecutive integers in the - 49, - 48, - 47..., 2004 column are:
-49,-48,-47…… 47, 48, 49, [don't forget 0]
Obviously, s (99) = 0
S(100)=S(99)+50=50

A round flower bed is 5m in diameter, and there is a circle of 2m wide path around it. What is the area of this path?

5 + 2 times 2 equals 9
9-5 equals 4
2 times 2 times 3.14 is 12.56
It's the area of the ring. It's the topic of the sixth grade~

The root lock of the equation x = 3-lgx is a (1,2) B (2,3) C (0,1) d (3,4) in the interval
The root lock of the equation x = 3-lgx is
A(1,2) B(2,3) C(0,1) D(3,4)

Let f (x) = x-3 + lgx
Then f (1) = - 20
So there are roots in (2,3) interval
Choose B
