Question

DAU COROANĂ!!! VA ROG URGENT​

Answer 1

Rezolvare:

a) x= 14,8cm - 8,9cm= 5,9cm

b) x= 6,7cm + 14,8cm = 21,5cm

c) 12,5cm : 5 = 2,5cm => x= 2,5cm * 3 x= 7,5cm

d) 1/3x= 11,2cm : 2

1/3x= 5,6cm

x= 3/3x

x= 5,6cm * 3 = 16,8

sau

x= 11,2cm + 5,6cm = 16,8

Sper ca te-am ajutat!

Answer 2

Răspuns:

Explicație pas cu pas:

a) x = 14,8 cm - 8,9 cm = 5,9 cm

b) x = 6,7 cm + 14,8 cm = 21,5 cm

c) 2/3 ·x + ³⁾x = ³⁾12,5 cm <=>

2x+3x = 3·12,5 cm =>

5x = 37,5 cm =>

x = 37,5 :5 => x = 7,5 cm

2/3 ·x = (2·7,5):3 = 15:3 = 5 cm

5 cm + 7,5 cm = 12,5 cm

d) x = 1/3 ·x +11,2 cm =>

x - 1/3 ·x = 11,2 cm

2/3 ·x = 11,2 cm

2x = 11,2 ·3 =>

2x = 33,6 cm

x = 33,6 cm : 2 => x = 16,8 cm

1/3 ·x = 16,8 :3 = 5,6 cm

5,6 cm + 11,2 cm = 16,8 cm
