y:0.125+y:0.5+y=9.9
Tìm y giúp mình với. Thank you
\(y\div0,125+y\div0,5+y=9,9\)
\(\Leftrightarrow y\times8+y\times2+y=9,9\)
\(\Leftrightarrow y\times\left(8+2+1\right)=9,9\)
\(\Leftrightarrow11y=9,9\)
\(\Leftrightarrow y=0,9\)
Trả lời:
y : 0,125 + y : 0,5 + y = 9,9
y : 0,125 + y : 0,5 + y : 1 = 9,9
y : ( 0,125 + 0,5 + 1 ) = 9,9
y : 1,625 = 9,9
y = 9,9 x 1,625
y = 16,0875. Vậy y = 16,0875
y:0.125+y:0.5+y=9.9

Ta có : y : 0.125 + y : 0.5 + y = 9.9
y × 8 + y × 2 + y = 9.9
y × ( 8 + 2 + 1 ) = 9.9
y × 11 = 9.9
y = 9.9 : 11
y = 0.9
Vậy y = 0.9
# chúc bạn học tốt #
y:0,125+y:0,5+y=9,9
yx8+yx2+yx1=9,9
yx(8+2+1)=9,9
yx11=9,9
y=9,9:11
y=0,9
\(\text{y:0.125+y:0.5+y=9,9}\)
\(\Leftrightarrow\text{y.8+y.2+y.1=9,9}\)
\(\Leftrightarrow y.\left(8+2+1\right)=9,9\)
\(\Leftrightarrow y.11=9,9\)
\(\Rightarrow y=0,9\)
chúc bạn học tốt !
y x 0.125 = 3.6+2.8 / 8
Tìm y giúp mk nha ! Thank you !
\(y.0.25=3.6+\frac{7}{20}\)
\(y.0.25=\frac{79}{20}=3.95\)
\(y=3.95:0.25=\frac{79}{5}=15.8\)
y x 0,125 = 3,6 + 2.8 : 8
y x 0,125 = 3,6 + 0,35
y x 0,125 = 3,95
y = 3,95 : 0,125
y = 31,6
k mik nha

Tìm y giúp mình nha .Cảm ơn
\(\text{y:0,125+y:0,5+y=9,9}\)
\(y:\left(0,125+0,5+1\right)=9,9\)
\(y:\frac{13}{8}=\frac{99}{10}\)
\(y=\frac{99}{10}.\frac{13}{8}\)
\(y=\frac{1287}{80}\)
học tốt
Tìm Y biết
y+y:0.5+y:0.25+y:0.125=15
giải giúp mình nhé
y + y : 0,5 + y : 0,25 + y : 0,125 = y + 2y + 4y + 8y = 15y = 15 => y = 15 : 15 = 1
y+y/0.5+y/0.2+y/0.125
\(y+\dfrac{y}{0,5}+\dfrac{y}{0,2}+\dfrac{y}{0,125}\\ =y+y\times\dfrac{10}{5}+y\times\dfrac{10}{2}+y\times\dfrac{1000}{125}\\ =y\times\left(1+2+5+8\right)\\ =y\times16\)
y + y + y : 0.5 + y : 0.25 + y :0.125 = 15
y + y + y : 0,5 + y : 0,25 + y : 0,125 = 15
y x 2 + y x 2 + y x 4 + y x 8 = 15
y x (2 + 2 + 4 + 8) = 15
y x 16 = 15
y = 15 : 16
y = 0,9375
k cho tớ nhé
y + y + y : 0.5 + y : 0.25 + y :0.125 = 15
yx2+yx1/2+yx1/4+yx1/8=15
yx(2+1/2+1/4+1/8)=15
yx23/8=15
y=15:23/8=120/23
\(=2y+2y+4y+8y=15\)
\(\Leftrightarrow16y=15\Leftrightarrow x=\frac{16}{15}\)
