Số túi gạo là x thì số tui nếp cũng là x như vậy khối lượng gạo và nếp là :

`15x+12x=945 `
` =>`Số lượng túi là `x=35` túi
Như vậy khối lượng gạo:

`15xx35=525kg `

Và khối lượng `12xx35=420kg`

20 tạ nha bạn

          Giải

Đổi: 12 tạ = 1200 kg, 80 yến = 800kg

Khối lượng gạo xe đó chở được là:

     1200 + 800 = 2000 (kg gạo)

          Đáp số: 2000 kg gạo

Giải:

   Đổi 12 tạ = 1 200 kg; 80 yến = 800 kg

Số ki-lô-gam gạo xe đó chở đc là:

      1 200 + 800 = 2 000 (kg)

          Đổi 2 000 kg = 2 tấn

                  Đ/S: 2 tấn gạo

Đổi 2 000 kg = 2 tấn bn làm hay ko tùy bn

Giải:

   Đổi 12 tạ = 1 200 kg; 80 yến = 800 kg

Số ki-lô-gam gạo xe đó chở đc là:

      1 200 + 800 = 2 000 (kg)

          Đổi 2 000 kg = 2 tấn

                  Đ/S: 2 tấn gạo

Đổi 2 000 kg = 2 tấn bn làm hay ko tùy bn

xe đó chở được số kg gạo là:

          18*50+15*20 = 1200 (kg)

đổi: 1200 kg = 12 tạ

                          đáp số: 12 tạ gạo.

Đáp án là 12 tạ gạo nha bạn.

Xe do cho dc so kg gao la:

18.50+15.20=1200 kg

1200 kg=12 ta

dap so :12 ta

dau cham la dau nhan nha bn

xe đó chở số kg gạo là:

    (50x18)+20x15=1200(kg)

       Đổi :1200kg=12 tấn

            Đáp số:12 tấn

12 tấn nha bạn chúc bạn học giỏi

Cân nặng của 18 bao gạo tẻ là:

50 x 18 = 900 (kg) = 9 tạ

Cân nặng của 15 bao gạo nếp là:

20 x 15 = 300 (kg) = 3 tạ

Số gạo xe đó chở được là:

9 + 3 = 12 (tạ)

Đáp số: 12 tạ gạo

Số gạo tẻ xe đó chở là:

   40 x 30 = 1200 (kg)

Số gạo nếp xe đó chở là:

   20 x 40 = 800 (kg)

Số gạo xe đó chở là:

   1200 + 800 = 2000 (kg)

                      Đ/S: 2000 kg

Số kg gạo nếp là: 

40 x 20 = 800 (kg)

Số kg gạo tẻ là :

30 x 40 = 1200 (kg)

Xe chở tổng số tấn gạo là: 

1200 + 800 = 2000 (kg) = 2 (tấn)

Xe đó chở:

\(30\cdot40+40\cdot20=2000\left(kg\right)\)

Đổi 2000kg=2 tấn

Hướng dẫn giải:

Số gạo tẻ xe chở được là :

25 x 50 = 1250 (kg)

Số gạo nếp xe chở được là :

30 x 25 = 750 (kg)

Tổng số gạo xe chở được là :

1250 + 750 = 2000 (kg)

Đổi 2000kg = 2 tấn

Đáp số : 2 tấn.

Tôi đéo biết

Khối lượng của 30 bao gạo tẻ là:

30 x 40 = 1200 ( kg )

Khối lượng của 40 bao gạo nếp là:

40 x 20 = 800 ( kg )

Đổi : 1200 kg = 1,2 tấn

         800 kg = 0,8 tấn

Xe đó chở được số tấn gạo là:

1,2 + 0,8 = 2 ( tấn )

               Đáp số : 2 tấn gạo

Xe đó chở số tấn gạo là:

(30×40)+(40×20)=2000(kg)=2(tấn)

                              Đáp số: 2 tấn
