Question

aflati suma numerelor :a,b,c stiind că:44:2=cx2=b:2. a=2x(c+b) a.198,b.155,c.110,d.165.

Answer 1

a + b + c = ?

44:2 = 2×c = b:2 2c = 44 : 2 = 22 c = 22:2 = 11

c = 11

2c = b/2 b= 2×2c = 4c b = 4c = 4×11 = 44

b = 44

a = 2×(c + b )= 2c + 2b = 2 × 11 + 2 × 44 = 22 + 88 = 110

a = 110

a + b + c = 110 + 44 + 11 = 165
