Question

jika diketahui 9×a=-27 dan -6:b=-3 tentukan nilai b-a?​

Answer 1

Penjelasan dengan langkah-langkah:

Jika:

9 × a = -27

-6 : b = -3

.

.

Nilai a dan b

9 × a = -27

a = -27/9

a = -3

.

-6 : b = -3

b = -3/-6

b = 3/6

b = 1/2

Maka,

b - a

1/2 - (-3)

= 1/2 - (-3/1).

= 1/2 - (-6/2)

= 7/2

= 3,5
