125 - 5 (x - 2) = 35
Tìm x: X x125=32250 ;39975:X=123
a) \(x.125=32250\)
\(x=32250:125\)
\(x=258\)
b) \(39975:x=123\)
\(x=39975:123\)
\(x=325\)
\(x\times125=32250\)
\(\Rightarrow x=258\)
_____
\(39975:x=123\)
\(\Rightarrow x=325\)
a)Xx125=32250
⇒ X=32250:125
⇒ X=258
b) 39975:X=123
⇒ X=39975:123
⇒ X=325

a, (1 + 3 + 5 + 7+ ... + 2003 + 2005) x (125125 x 127 - 127127 x125)
= (1 + 3 + 5 +...+2003 + 2005) x (125 x 1001 x 127 - 127x1001 x 125)
= (1 + 3 + 5 +...+ 2003 + 2005) x 0
= 0
b; 1000 x 0,04 - 100 : 2,5 + 10 x 0,4
= 100 x 0,4 - 100 x 0,4 + 10 x 0,4
= 0 + 4
= 4
Tính
120 x 999 + 120
2 x 4 x 0,8 x 5 x 2,5 x125
\(\frac{120\times999+120}{2\times4\times0,8\times5\times2,5\times125}\)
\(=\frac{120\times1000}{\left(125\times0,8\right)\left(4\times2,5\right)\left(2\times5\right)}\)
\(=\frac{120000}{100\times10\times10}\)
\(=\frac{120000}{10000}\)
\(=\frac{12}{1}=12\)
