Question

Calcule o Valor de X usando o Teorema de Tales.

Answer 1

a)

6/18 = 4/x Forma de fracao

multiplica cruzado:

6x = 4 × 18

6x = 72

x = 72÷6

x=12

b)

5/20 = 4/x

multiplica cruzado:

5x = 4 × 20

5x = 80

x = 80÷5

x = 16

c)

4/10 = x/9

multiplica cruzado:

10x = 9 × 4

10x = 36

x = 36÷10

x = 3,6

d)

6/3 = 4/x

multiplica cruzado:

6x = 4 × 3

6x = 12

x = 12÷6

x = 2

e)

2/x = 6/9

multiplica cruzado:

6x = 2 × 9

6x = 18

x = 18÷6

x = 3
