Question

Determine as medidas de x e y

Answer 1

Resposta:

Explicação passo-a-passo:

a)

x/x+10 = 10/15

15x = 10(x + 10)

15x = 10x + 100

15x - 10x = 100

5x = 100

x = 100/5

x = 20

20/10 = 18/y

20y = 18.10

y = 180/20

y = 9

b)

x/9 = 9/15

15x = 9.9

x = 81/15

x = 27/5

6/y = 9/24

9y = 24.6

y = 144/9

y = 16
