Question

Tìm x. Biết: 

a) x/17= 60/204

b) 6+x/33= 7/11

c) 12+ x / 43 - x= 2/3

d) 1< 6/x < 2

Answer 1

Bạn nào giúp mình, mình lại 3 cái!

Answer 2

Mình 3 cái

Answer 3

a) \(\frac{x}{17}=\frac{60}{204}< =>x=5\)

b) \(6+\frac{x}{33}=\frac{7}{11}< =>\frac{x}{33}=\frac{7}{11}-6=-\frac{59}{11}< =>x=-177\)

c) \(12+\frac{x}{43}-x=\frac{2}{3}< =>-\frac{42}{43}x=-\frac{34}{3}< =>x=\frac{731}{63}\)

d) \(1< \frac{6}{x}< 2< =>6>x>3\)

Answer 4

\(\frac{x}{17}=\frac{60}{204}\\ =>x.204=17.60\\ x.204=1020\\ x=1020:204\\ x==5\)

Answer 5

\(6+\frac{x}{33}=\frac{7}{11}\)

\(\frac{x}{33}=\frac{7}{11}-6\)

\(\frac{x}{33}=\frac{-59}{66}\)

=>x.66=33.(-59)

x.66=-1947

x=-1947:66

x=29

vậy x=29
