Các bạn giúp mk nha
Tính:
75- ( 6/13 + 3/17 - 3/19 )
M= -------------------------------------
275- ( 22/13 + 11/17 - 11/19 )
giúp mk mk tick cho
75-6/13+3/17-3/19|275--22/13+11/17-11/19
Tính nhanh: M = \(\frac{75-\frac{6}{13}+\frac{3}{17}-\frac{3}{19}}{275-\frac{22}{13}+\frac{11}{17}-\frac{11}{19}}\)
giúp mik mn
\(M=\frac{75-\frac{6}{13}+\frac{3}{17}-\frac{3}{19}}{275-\frac{22}{13}+\frac{11}{17}-\frac{11}{19}}\)
\(=\frac{3.25-\frac{2}{13}+\frac{1}{17}-\frac{1}{19}}{11.25-\frac{2}{13}+\frac{1}{17}-\frac{1}{19}}\)
\(=\frac{3}{11}\)
Vậy: \(M=\frac{3}{11}\)
75-3(2/13+1/17-3/19) 75-3 72 3
-------------------------------------------------=------- =-------=----
275-11(2/13+1/17-1/19 275-11 264 11
làm thế này nhanh hơn bn tôi co đơn à vì cô mình dạy như vậy
a,-8/3+7/5+-71/15<x<-13/7+19/14+-7/2
b,-19/6+-15/2+11/3<x<-5/4+19/12+-10/3
c,-6/7+3/35<x<-2/5+3/7
d,x=3/4+1/-12
e,x/14=1/7+-3/14
f,11/18+13/6=85/x
g,8/17+5/17<x/17<6/17+9/17
mong các bn giúp đỡ mk vs mk cần rát gấp
ai nhanh giúp mk thì mk tick cho 3 tick mk thề có lòng tự trọng
ai lm nhanh mk cho 10 tick lun nhanh nha đang cần gấp
các bn lm đến đâu cx dc miễn là lm hộ mk cái ạ, ai đang lm vào nhắn tin vs mk để mk bít nha
a; \(-\dfrac{8}{3}+\dfrac{7}{5}-\dfrac{71}{15}< x< -\dfrac{13}{7}+\dfrac{19}{14}-\dfrac{7}{2}\)
-\(\dfrac{19}{15}\) - \(\dfrac{71}{15}\) < \(x\) < -\(\dfrac{1}{2}\) - \(\dfrac{7}{2}\)
-6 < \(x\) < -4
vì \(x\) \(\in\) Z nên \(x\) = -5
- \(\dfrac{19}{6}+\dfrac{-15}{2}+\dfrac{11}{3}\) < \(x\) < - \(\dfrac{5}{4}\) + \(\dfrac{19}{12}\) - \(\dfrac{10}{3}\)
- \(\dfrac{32}{3}+\dfrac{11}{3}< x< \) \(\dfrac{1}{3}\) - \(\dfrac{10}{3}\)
-7 < \(x\) < - 3
Vì \(x\in\) Z nên \(x\in\) {-6;-5;-4}
[2\11*13+2\13*15+2\15*17+2\17*19+2\19*21]*462-y=19
ai giải giúp mk đầu tiên mk tick cho
\(A=\frac{75-\frac{6}{13}+\frac{3}{17}-\frac{3}{19}}{275-\frac{22}{13}+\frac{11}{17}-\frac{11}{19}}\)
Mik đag cần gấp thanks!
A = \(\frac{75-\frac{6}{13}+\frac{3}{17}-\frac{3}{19}}{275-\frac{22}{13}+\frac{11}{17}-\frac{11}{19}}\)
A = \(\frac{3.\left(25-\frac{2}{13}+\frac{1}{17}-\frac{1}{19}\right)}{11.\left(25-\frac{2}{13}+\frac{1}{17}-\frac{1}{19}\right)}\)
A = \(\frac{3}{11}\)
tinh nhanh
M=\(\frac{75-\frac{6}{13}+\frac{3}{17}-\frac{3}{19}}{275-\frac{22}{13}+\frac{11}{7}-\frac{11}{9}}\)
