b) (-10) * __ =90

c) __ * (+5) = +30


d) __ * (-7) = -35

Answer 1

Respuesta:

a)

$( - 4)(x) = - 24 \\ x = \frac{ - 24}{ - 4} \\ x = 6$

b)

$( - 10)(x) = 90 \\ x = \frac{90}{ - 10} \\ x = - 9$

c)

$(x)(5) = 30 \\ x = \frac{30}{5} \\ x = 6$

d)

$(x)( - 7) = - 35 \\ x = \frac{ - 35}{ - 7} \\ x = 5$
