b) 20 + (-6) x ( -4) : 4 =
c) 30 x (-2) : 6 – (- 15) =
d) 20 : (-5) : (-2) =

es

Answer 1

Respuestas:

a $\frac{-15}{5+6x\left(-3\right)}=-\frac{15}{5-18x}$

b $\frac{20+\left(-6\right)x\left(-4\right)}{4}=5+6x$

c $\frac{30x\left(-2\right)}{6-\left(-15\right)}=\quad -\frac{20x}{7}$

d $20\div \left(-5\right)\div \left(-2\right)=2$
