giải lun nha
x-(4x/8+1x/8)=45/4
x-5x/8=45/4
-4x=45/4.8
-4x=90
x=90/(-4)
x=22,5
nếu đúng thì cho mk **** nha mk đang cần
ai tích mình mình tích lại cho
\(\text{Tìm x , biết : }\)
\(a.\frac{1}{5.8}+\frac{1}{8.11}+\frac{1}{11.14}+...+\frac{1}{x\left(x+3\right)}=\frac{101}{1540}\)
\(b.x-\left(\frac{50x}{100}+\frac{25x}{200}\right)=\frac{45}{4}\)
\(c.1+2+3+4+...+x=820\)
Ai làm nhanh mk cho 20 tích
TÌM X:
\(x-\left(\frac{50x}{100}+\frac{25x}{100}\right)=11\frac{1}{4}\)
Tìm x:
a) x - (\(\frac{50x}{100}+\frac{25x}{200}\)) = \(11\frac{1}{4}\)
b) (x - 5) . \(\frac{30}{100}\) = \(\frac{200x}{100}\) + 5
Tìm x:
a) \(x-\left(\frac{50x}{160}+\frac{25x}{200}\right)=11\frac{1}{4}\)
b)\(\left(x-5\right)\cdot\frac{30}{100}=\frac{200x}{100}+5\)
Giúp mình nhanh với, cảm ơn các bạn rất nhiều!
x-(50x/100+25x/200)=45/4
Tìm x, biết:
a, \(x-\left(\frac{50x}{100}+\frac{25x}{200}\right)=11\frac{1}{4}\) b,\(\left(x-5\right).\frac{30}{100}=\frac{200x}{100}+5\)
c,\(\frac{x+1}{2}=\frac{8}{x+1}\) d, \(x:\left(9\frac{1}{2}-\frac{3}{2}\right)=\frac{0,4+\frac{2}{9}-\frac{2}{11}}{1,6+\frac{8}{9}-\frac{8}{11}}\)
x - \(\text{}\text{}\left(\dfrac{50x}{100}+\dfrac{25x}{200}\right)\)= \(11\dfrac{1}{4}\)
\(x-\frac{25x}{100}=60-x+\frac{25x}{100}\)
tim x biet
a)2^x+2 -2^x=96
b)x-(50x/100+25x/200)=111/4
c) (x-5).30/100=200x/100+5
