Question

Calcule mentalmente o valor de X



​

Answer 1

Olá...

Explicação passo-a-passo:

a)

3/15 = x/5

15x = 15

x = 15/15

x = 1

3/15 = 1/5

b)

8/x = 12/3

12x = 24

x = 24/12

x = 2

8/2 = 12/2

Bons estudos.

Answer 2

A) 3/15 = x/5

15 • x = 3 • 5

15x = 15

x= 15/15

x= 1

B)8/x = 12/3

x • 12 = 8 • 3

12x = 24

x= 24/12

x= 2
