Question

ayudaaaaaaaa calcula el valor de x

Answer 1

35.

x + 20 + 15 = 71

x + 35 = 71

x = 71 - 35

x = 36 cm

36.

BC = x + 3

x + 3 + x + 3 + 3x - 6 = 80

5x = 80

x = 16 cm

37.

BC = 9 cm

CD = 12 cm

x - 1 = 9 + 12

x - 1 = 21

x = 1 + 21

x = 22 cm

38.

2(MN) = 36 cm

MN = 18 cm

18 + 36 + 4x - 2 = 100

4x + 52 = 100

4x = 100 - 52

4x = 48

x = 12 cm
