Answer 1

Respuesta:

[tex]=61\frac{1}{10}[/tex]

Explicación paso a paso:

[tex]-42\div \left(-35+42\right)+\left(-14+9\cdot \:7\right)\div \left(-5-5\right)-8\left(-9\right)\\\\-35+42\\\\=7\\\\=-42\div \:7+\left(-14+9\cdot \:7\right)\div \left(-5-5\right)-8\left(-9\right)\\\\-14+9\cdot \:7\\\\=-14+63[/tex]

[tex]=49\\\\=-42\div \:7+49\div \left(-5-5\right)-8\left(-9\right)\\\\-5-5\\\\=-10\\\\=-42\div \:7+49\div \left(-10\right)-8\left(-9\right)\\\\-42\div \:7\\\\=-6\\\\=-6+49\div \left(-10\right)-8\left(-9\right)[/tex]

[tex]49\div \left(-10\right)\\\\=\frac{49}{\left(-10\right)}\\\\=-6+\frac{49}{\left(-10\right)}-8\left(-9\right)\\\\8\left(-9\right)\\\\=-72\\\\=-6+\frac{49}{\left(-10\right)}-\left(-72\right)\\\\-6+\frac{49}{-10}[/tex]

[tex]=-6-\frac{49}{10}\\\\=-\frac{6\cdot \:10}{10}-\frac{49}{10}\\\\=\frac{-6\cdot \:10-49}{10}\\\\=\frac{-109}{10}\\\\=-\frac{109}{10}\\\\=-\frac{109}{10}-\left(-72\right)\\\\=-\frac{109}{10}+72\\\\=\frac{611}{10}[/tex]

[tex]=61\frac{1}{10}[/tex]
