Question

2. Resuelve las siguientes ecuaciones.

a)20 + 8 = 28+ 25 + 8 = 61
b) 30 + 23 = 53+20 + 59 = 132
c) 5 + 12 = 17
d) 20 – 4 = 16+ 9 = 25
e) 50 – 10 = 40 – 12= 28

Answer 1

Respuesta:

Explicación paso a paso:

a)20 + 8 = 28+ 25 + 8 = 61

28 = 61 = 61

b) 30 + 23 = 53+20 + 59 = 132

53 = 132 = 132

c) 5 + 12 = 17

17 = 17

d) 20 – 4 = 16+ 9 = 25

14 = 25 = 25

e) 50 – 10 = 40 – 12= 28

40 = 28 = 28
