9d=​

Answer 1

¡Hola!

Respuesta:

5d+6u = 56

9u+2c+3d = 239

70+300+4 = 374

9d =​ 90

Explicación paso a paso:

5 D = 5 x 10 = 50

6 U = 6 x 1 = 6

50 + 6 = 56

2 C = 2 × 100 = 200

3 D = 3 × 10 = 30

9 U = 9 × 1 = 9

200 + 30 + 9 = 239

3 C = 3 × 100 = 300

7 D = 7 × 10 = 70

4 U = 1 × 4 = 4

300 + 70 + 4 = 374

9 D = 9 × 10 = 90

Espero poder ayudarte.
