Question

Daca a supra e= b supra f=c supra g = d supra h =4 , atunci calculeaza 10-a+b+c+d supra e+f+g+h. Ajutati-ma va rog dau coroana

Answer 1

a/e=b/f=c/g=d/h=4

a=4e

b=4f

c=4g

d=4h

____ +

a+b+c+d=4(e+f+g+h)

10 - 4(e+f+g+h)/(e+f+g+h) =

10-4=

6

Answer 2

a / e = b / f = c / g = d / h = 4

⇒  a = 4 e ;    b = 4 f;   c = 4 g;   d = 4 h

10 - ( a + b + c + d ) / ( e + f + g + h ) =  4

= 10 - ( 4 e + 4 f + 4 g + 4 h ) / ( e + f + g + h ) =

= 10 - 4 ( e + f + g + h ) / ( e + f + g + h ) =

= 10 - 4 × 1 =

= 10 - 4 =

= 6
