Question

qual é o valor do número inteiro N quando

a) N : ( –5 ) = –8

b) ( –160 ) : N = + 20

c) ( –360 ) : ( – 12 ) = N

d) N : ( + 21 ) = 0 ​

Answer 1

a) N : ( –5 ) = –8

N = - 8 . - 5

N = 40

b) ( –160 ) : N = + 20

( - 160) = 20 . N

( - 160) = 20N

N = - 160/20

N = - 8

c) ( –360 ) : ( – 12 ) = N

( - 360) = - 12N

N = - 360/- 12

N = 30

d) N : ( + 21 ) = 0

N = 21
