x*18 + x*2 = 160
=> 18x + 2x = 160
=> 20x = 160
=> x = 8
\(x\times18+x\times2=160.\)
\(x\times\left(18+2\right)=160\)
\(x\times20=160\)
\(x=160:20\)
\(x=8\)
x*18 + x*2 = 160
=> 18x + 2x = 160
=> 20x = 160
=> x = 8
\(x\times18+x\times2=160.\)
\(x\times\left(18+2\right)=160\)
\(x\times20=160\)
\(x=160:20\)
\(x=8\)
X x 18 + X 2 = 160
x+x+x+x=160.x=?
Tim x:
2x+2x+2=160
các bn giúp mk nha
[x+2]+[x+4]+[x+6]+...+[x+20]=160
[1/2+1/4+1/8+...+1/64]/x=3/8
làm giúp mình nha ai nhanh thì tick
tìm x
a 6 x + 15x8=12.(19-x)
b 160-(35: x +3 )x15=15
c 2x - ( 1309:11-19)-2=0
d (x-7)x(2x-16)=0
giúp mk với
C= 46 - 45 + 44 - 43 + 42 - 41 + ... + 2- 1
G = 2 x 31 x 12 + 4 x 6 x 42 + 8 x 27 x 3
I = 7 x 48 x 6 + 21 x 12 x 2 + 14 x 40 x 3
K = 1 + 7 + 8 + 15 + 23 + ... + 160
tìm x
(x+5)+(x+7)+(x+9)+...,........... +(x+15)=160
tìm x
a,134:(x-3)=35+160:5
b,[(10-x).2+]:3-2=3
tl nhớ kb vs mk na
tim x
2 * X * 3 - 160 = 710
giup minh voi duoc ko
