\(\left(\frac{1}{25}-\frac{1}{30}\right).150+1,03:1,03.\left(x-1\right)=3\)
\(\frac{1}{150}.150+1.\left(x-1\right)=3\)
\(1+\left(x-1\right)=3\)
\(x-1=3-1=2\)

[1/(25×26) + 1/(26×27) + ... + 1/(29×30)] × 150 + 1,03/[ 1,03 × (x-1)= 22
Mình đang cần gấp!
Đáp án thui cũng đc!
(1/25*26+1/26*27+........+1/29*30)*150+10,3:[1,03(x-1)]=22
\(\left(\frac{1}{25.26}+\frac{1}{26.27}+.......\frac{1}{29.30}\right).150+1,03:\left[1,03.\left(x-1\right)\right]=22\)
Biểu thức nào dưới đây có kết quả bằng 1,03 x 15,57?
A. (1,03 + 5,07) + (1,03 + 10,5)
B.1,03 x 5,07 + 10,5
C.1,03 x 5,07 + 1,03 x 10,5
D.(1,03 x 5,07) x (1,03 x 5,07)
\(\left(\frac{1}{25.21}+\frac{1}{26.27}+........+\frac{1}{29.30}\right).150+103\left[1,03+\left(x+1\right)\right]=22\)
\(\left(\frac{1}{25.26}+\frac{1}{26.27}+........+\frac{1}{29.30}\right).150+103:\left[1,03+\left(x+1\right)\right]=22\)
\(\orbr{\begin{cases}1\\25X26\end{cases}}+\frac{1}{26X27}+.......+\frac{1}{29x30}\)đóng ngoặc X 150 + 103 ; 1,03 x mở ngoặc x - 1 đóng ngoặc = 22
1+1,03 : "10,3 (x-1) "=11
(((((tim x )))))))))))
6*(2/5*x+3)=3/5
1+1,03:[10,3*(x-1)]=11
Ai trả lời nhanh nhất thì kb nha.
