Question

ecuații: a×2=60, 3×b=600, a+305=1000, 164+b=900, c-104=397,
400-d=45, 800÷c=2, d÷7 =70​

Answer 1

Răspuns:

Salut !

a x 2 = 60 => a = 30

3 x b = 600 => b = 200

a + 305 = 1000 => a = 1000-305 = 695

164 + b = 900 => b = 900 - 164 = 736

c - 104 = 397 => c = 104 + 397 = 501

400 - d = 45 => d = 400 - 45 = 355

800 : c = 2 => c = 800: 2 = 400

d : 7 = 70 => d = 70 x 7 = 490

Sper ca te-am ajutat
