Ответ:
\(x : 1.2 = 0.144\)
\(x = 0.144 \cdot 1.2 = 0.1728\)
Ответ: \(x = 0.1728\).
\(x \cdot 1.2 = 36\)
\(x = 36 : 1.2 = 30\)
Ответ: \(x = 30\).
\(0.013y = 1.69\)
\(y = 1.69 : 0.013 = 130\)
Ответ: \(y = 130\).
\(2(y + 0.13) = 5.46\)
\(y + 0.13 = 5.46 : 2 = 2.73\)
\(y = 2.73 - 0.13 = 2.6\)
Ответ: \(y = 2.6\).
\(3(6 - x) = 11.1\)
\(6 - x = 11.1 : 3 = 3.7\)
\(-x = 3.7 - 6 = -2.3\)
\(x = 2.3\)
Ответ: \(x = 2.3\).
\(0.2x + 13.5 = 27\)
\(0.2x = 27 - 13.5 = 13.5\)
\(x = 13.5 : 0.2 = 67.5\)
Ответ: \(x = 67.5\).
\(0.3x + 1.5x = 5.76\)
\(1.8x = 5.76\)
\(x = 5.76 : 1.8 = 3.2\)
Ответ: \(x = 3.2\).
\(0.3x + 0.4x = 15.47\)
\(0.7x = 15.47\)
\(x = 15.47 : 0.7 = 22.1\)
Ответ: \(x = 22.1\).
\(2x + 3.5x = 30.25\)
\(5.5x = 30.25\)
\(x = 30.25 : 5.5 = 5.5\)
Ответ: \(x = 5.5\).
