Ta có : a chia 6 dư 2 => a - 2 chia hết cho 6 => a - 2 + 12 chia hết cho 6 => a + 10 chia hết cho 6

a chia 7 dư 4 => a - 4 chia hết cho 7 => a - 4 + 14 chia hết cho 7 => a + 10 chia hết cho 7

=> a + 10 chia hết cho 6 và 7

=. a + 10 thuộc BC ( 6 ; 7 )

Mà BCNN ( 6 ; 7 ) = 42

=> a + 10 thuộc B ( 42 ) = { 0 ; 42 ; ... }

=> a + 10 chia 42 dư 42

=> a chia 42 dư 32

Vậy số a chia cho 42 dư 32

a: Tổng vận tốc hai xe là 12+5=17(km/h)

Hai xe gặp nhau sau khi đi được: 14/17(giờ)

Hai xe gặp nhau lúc:

8h+14/17h\(\simeq\)8h49p

b: Chỗ hai người gặp nhau cách B:

\(\dfrac{14}{17}\cdot5=\dfrac{70}{17}\left(km\right)\)

a, Thời gian 2 người gặp nhau là:

\(14:\left(12-5\right)=2\) (giờ)

Đến số giờ thì người đi xe đạp đuổi kịp người đi bộ là:

\(8+2=10\) (giờ)

b, Chỗ người đi xe đạp đuổi kịp người đi bộ cách B là:

\(5\cdot2=10\left(km\right)\)

Đáp số: \(a,10\) giờ, \(b,10km\)

Ta biết: \(1kg=0,001\) tấn

\(\rightarrow85kg=0,085\) tấn

\(\Rightarrow D.0,085\) 

Ta có:

tấn     tạ     yến    kg      hg     dag    g

mỗi đơn vị cách nhau 10

ta thấy 1kg=0,01 tấn

Nên 85kg=0,085 tấn

vậy D là đáp án đúng

hok tốt!!

Khoảng cách giữa hai phần tử là: `8-2=6` 

Số phần tử của G là:

`(386-2):6+1=65` (số hạng) 

Vậy: ... 

Kkk

Gọi số lập được có dạng là \(\overline{abcd}\)

a có 3 cách chọn

b có 3 cách chọn

c có 2 cách chọn

d có 1 cách chọn

Do đó: Có \(3\cdot3\cdot2\cdot1=18\left(cách\right)\)
