[3.x-2mu4].7mu3=2.7mu4
tra loi nhanh nha
A= 7+7mu3+7mu5+ ....... +7mu199 chung to A chia het cho 35
ai giai mau co loi gia dung minh se tich cho
1440/[41-(x-5)=2mu4 *3
\(\frac{1440}{41-\left(x-5\right)}=2^4.3\)
\(\Rightarrow\left[41-\left(x-5\right)\right]2^4.3=1440\)
\(\Rightarrow\left[41-\left(x-5\right)\right].48=1440\)
\(\Rightarrow41-\left(x-5\right)=30\)
\(\Rightarrow x-5=11\)
\(\Rightarrow x=16\)
Vậy \(x=16\)
tim x biet: |x-2|-|2x+3|-x=-2
nho tra loi nhanh giup minh nha
4.(x+1)+3.x(x+2 )
giup mk nha , ai tra loi nhanh va dung thi mk se tick
4.(x+1)+3.x(x+2 )
= 4x + 4 + 3x2+6x
= 10x + 3 + 3x2
may ban tra loi nhanh nha minh can gap
\(\sqrt{4x-20}-3\sqrt{\dfrac{x-5}{9}}=2\)
\(\sqrt{4x-20}\)- 3\(\sqrt{\dfrac{x-5}{9}}\)=2
= \(\sqrt{4x-4.5}\)-3\(\sqrt{\dfrac{x-5}{9}}\)=2
= 2.2\(\sqrt{x-5}\)-3.9\(\sqrt{x-5}\)=2
= -23\(\sqrt{x-5}\)=2
= -23.x-5=2
=-23x=2+5
-23x =7
x =\(\dfrac{-7}{23}\)
x= -0.3
Bai 1: Tim so tu nhien x, biet
(x+1)+(x+2)+(x+3)+....+(x+100)=5750
Bai 2; Tinh nhanh
96:8=
Cac ban tra loi nhanh ho minh nha minh tick cho
1) (x+1)+(x+2)+(x+3)+...+(x+100) = 5750
(x+x+x+...+x)+(1+2+3+...+100)= 5750
100x + 5050 = 5750
100x = 5750 - 5050
100 x = 700
x = 700 :100
x = 7
2) 96 : 8= 12
Bài 1
(x+1)+(x+2)+(x+3)+....+(x+100)=5750
x+1+x+2+x+3+...+x+100=5750
(x+x+x+...+x)+(1+2+3+...+100)=5750 (có 100 số x)
100x+(100.101:2)=5750
100x+5050=5750
100x=5750-5050
100x=700
x=7

24*3 =??
cac ban tra loi xong kb voi mk nha
ai tra loi nhanh va dung mk tk
X+3=5+10
Ai nhanh, ai dung mk k, ai tra loi cau hoi nay thi nho kb vs mk do, nho k mik nha
x + 3 = 5 + 10
x + 3 = 15
x = 15 - 3
x = 12
x + 3 = 5 + 10
x + 3 = 15
x = 15 - 3
x = 12
mk nhanh nhất và đúng nhất
X + 3 = 5 + 10
X= 15 - 3
X = 12
5 x 2 + 3 x 3 = ?
Ai nhanh, ai dung, mk k. Ai tra loi cau hoi nay thi nho tick cho mk va nho kb nha
AI TICK MINH, MINH TICK LAI
5x2+3x3=19
Mình nhanh nhất nhè, khoanh cho mình nhé, mình kb nhé
