Question

8) Qual é o valor do número inteiro N quando:
a)
N : (– 6) = +9
b)
(– 150) : N = + 15
c)
(– 360) : (– 12) = N
d)
(– 625) : ( –25) = N

Answer 1

Resposta:

a)

\sf N\div(-5)=-8N÷(−5)=−8

\sf N=(-8)\cdot(-5)N=(−8)⋅(−5)

\sf N=40N=40

b)

\sf (-160)\div N=-8(−160)÷N=−8

\sf -8N=-160−8N=−160

\sf N=\dfrac{-160}{-8}N=−8−160

\sf N=20N=20

c)

\sf (-360)\div(-12)=N(−360)÷(−12)=N

\sf N=(-360)\div(-12)N=(−360)÷(−12)

\sf N=30N=30

d)

\sf N\div(+21)=0N÷(+21)=0

\sf N=21\cdot0N=21⋅0

\sf N=0N=0
