REPEDE DAU COROANA!! ​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

a + c = 135

b = 27

a + b + c = a + c + b = 135 + 27 = 162

b)

a + c = 53

a + 27 + c = a + c + 27 = 53 + 27 = 80

c)

a + b + c = 132

b = 75

a + c = 132 - b = 132 - 75 = 57

d)

a = 132

b + c = 75

a - b - c = a - (b + c) = 132 - 75 = 57

e)

a - b - c = 73

a = 79

a - (b + c) = 73

79 - (b + c) = 73

b + c = 79 - 73 = 6

f)

a - b = 27

c = 53

a - (b - c) = a - b + c = 27 + 53 = 80

g)

a - c = 29

b = 11

a + (b - c) = a + b - c = a - c + b = 29 + 11 = 40
