Question

-[-(5)(-2)+(-5+7-2)-(-15)/(5)+(-4)/8]

Answer 1

Respuesta:

= -25/2

Explicación paso a paso:

$=-\left(-\left(5\right)\left(-2\right)+\left(-5+7-2\right)-\frac{-15}{5}+\frac{-4}{8}\right)$

$=-\left(5\cdot \:2-5+7-2-\frac{-15}{5}+\frac{-4}{8}\right)$

Simplifica

$=-\left(-\frac{1}{2}+10+7-5-2-\left(-3\right)\right)$

$=-\left(10-5+7-2+3-\frac{1}{2}\right)$

Sumar/restar

$=-\left(-\frac{1}{2}+13\right)$

$\boxed {=-\frac{25}{2}}$
