               Answer:

From the first division, we formulate the relation as A= 54L+38, Where L is some integer. The second relationship gives A=18 × 14+ R with r ∈ n and $0

A=54x + 38=18 × 3x + 18 × 2 + 2=18(3x + 2)+2

Hence R=2 and A= 18 × 4 + 2= 254

Answer is: A + R=256

Good luck

9x2=18

Bạn chép ở đâu đấy tiến sao mk thấy mk làm đâu rồi

Let a,b be the two natural numbers. Suppose that a>b, we have a+b=3(a−b). From this, 2b=a, or a/b=2.  

1000=1+999=2+998=⋯=499+501=500+500,

which implies that there are 500 pairs of such positive integers. Đáp số: 500

   Đúng 100%

Đúng ko

theo mk bạn đúng rồi 

mk cũng là:5%

So the numbers satisfy is: 60,120,...,480
