= 1 nha bn kick mik nhé

8 và 18

Ta có dãy số: 101,103,105,...,999

TBC các số lẻ có 3 chữ số là:

(101+ 999) : 2 = 550

             Đáp số 550

1,25 - 0,25 x 5  không được vì 1,25 < 0,25 * 5

Lớp 5 chưa học

tính nhanh:(1,25-0,25*5)*(1,1*1,2*1,3*1,4*1,5)=0x(1,1x1,2x1,3x1,4x1,5)

                                                                   =0

k nha

=1700m2

Ta có: a - b = 2.(a + b)

=> a -b = 2a + 2b

=> 

a) x + 3,5 = 7

         x = 7 - 3,5

         x = 3,5

b) x - 7,2 = 6,4

         x = 6,4 + 7,2

         x = 13,6

 Sau khi mua váy, bạn chắc chắn còn 3.000 tiền thừa. Bạn gửi trả bố 1.000, trả mẹ 1.000 nên chỉ còn nợ mỗi người: 50.000 - 1.000 = 49.000, tổng cộng nợ bố và mẹ: 49.000 + 49.000 = 98.000. Và bạn còn 1.000 tiền thừa.

Đến đây:

- Nếu bạn đưa nốt 1.000 cho bố hoặc mẹ thì bạn chỉ còn nợ bố và mẹ: 98.000 - 1.000 = 97.000 - bằng giá trị cái váy bạn mua.

- Nếu bạn giữ lại 1.000 và 97.000 giá trị cái váy sẽ có tổng là 98.000, bằng số tiền nợ bố mẹ

Do đó, bạn sẽ không bị mất đồng nào.
