\(\left(x-2\right)\div37=\left(1008+1\right)\times\frac{2}{37}\)
\(\left(x-2\right)\div37=1009\times\frac{2}{37}\)
\(\left(x-2\right)\div37=\frac{2018}{37}\)
\(x-2=\frac{2018}{37}\times37\)
\(x-2=2018\)
\(x=2018+2\)
\(x=2020\)
1, (\(x\)+1)+(\(x\)+4)+(\(x\)+7)+...+(\(x\)+28)=155
2, (\(x\)-2):37=(1008+1) x \(\frac{2}{37}\)
tìm x, biết: \(\frac{x-1}{5}+\frac{x-1}{7}+\frac{x-1}{9}+....+\frac{x-1}{35}+\frac{x-1}{37}=0\)
Tìm x ,biết:
\(2-\left(\frac{37}{7}+x-3\right)\times\frac{49}{11}=0\)
X × 2/3-1/4=37/12
Yêu cầu là tìm x biết
A = 2 / 1 x 2 x 3 + 2 / 2 x 3 x 4 + 2 / 3 X 4 X 5 +.....+ 2 / 36 x 37 x 38 + 2 / 37 x 38 x 39
Tìm A
Tìm x
(\(\left(1+\frac{1}{2}\right)x\left(1+\frac{1}{3}\right)x\left(1+\frac{1}{4}\right)x...x\left(1+\frac{1}{x}\right)=1008\frac{1}{2}\)
tìm x
( x+1)+(x+2)+(x+3).......(X+37)=999
Tìm a
a) 24+3x(5xa)=27
b) (1,5 - a ):\(\frac{3}{4}=\frac{20}{9}\)
c) a x \(2\frac{1}{5}-\)a x\(\frac{4}{7}=\frac{5}{77}\)
d) {37 -2 x (a - 3,25)} : 5 = 7,06
Tính nhanh
Ạ) ( 12 x 2 + 12 x 4 - 12 x 6) : ( 2 + 4 + 6 +... + 12 + 14)
b) 37 x 49 + 37 x 2 x 25 + 37
