Ta có:

KLNT của Oxygen (O) là 16, từ đó, suy ra:

KLNT X = O*2 = 16*2 = 32

=> Nguyên tử X chính là Sulfur (S) với KLNT là 32 (amu)

Ta có:

\(\dfrac{81}{54}=\dfrac{81\div27}{54\div27}=\dfrac{3}{2}\)

Cậu bé có bánh mì, một quả trứng luộc, và sữa cho bữa sáng

\(2-2+2-2=0\\ 2-2+\left(2\div2\right)=1\\ 2\div2+2\div2=2\\ 2\times2-2\div2=3\\ 2\times2+2-2=4\\ 2\times2+2\div2=5\\ 2\times2\times2-2=6\\ 2^{\sqrt{2}}\times2+\sqrt{2}\approx7\\ 2+2+2+2=8\\ 2^{2+\sqrt{2}}-\sqrt{2}\approx9\\ 2\times2\times2+2=10\)

Đây là đáp án gần chính xác nhất với đề bài yêu cầu nhé!

Gọi một nửa tổng 2 số chẵn cần tìm là x, số bé là y và số lớn là z

Ta có:

 \(x=\dfrac{182}{2}=91\)

Vì 91 là số lẻ nên:

\(y=x-1\\ z=x+1\)

Ta có:

\(y=x-1=91-1=90\\ z=x+1=91+1=92\)

=> Số bé (y) = 90

Ta có:

\(\dfrac{-4}{11}=\dfrac{x}{22}=\dfrac{40}{y}\\ \Rightarrow x=\dfrac{-4}{11}\cdot22=-8\\ \Rightarrow y=\dfrac{22\cdot40}{-8}=-110\)

Vậy \(\left(x;y\right)\) thỏa mãn đề bài là: \(\left(-8;-110\right)\)

b, \(2\cdot\left(x+7\right)-6=18\\ 2\cdot\left(x+7\right)=18+6=24\\ x+7=\dfrac{24}{2}\\ x+7=12\\ x=12-7\\ x=15\)

There are many things in this world you can interested in, but there is only one thing make you happy, is your house with your family live in. My house is not a very big, but not very small..
