\(\dfrac{y}{2}+\dfrac{y+y}{3}+\dfrac{y+y+y}{4}=\dfrac{13}{12}\)
\(\dfrac{1}{2}y+\dfrac{2}{3}y+\dfrac{3}{4}y=\dfrac{13}{12}\)
\(y\left(\dfrac{1}{2}+\dfrac{2}{3}+\dfrac{3}{4}\right)=\dfrac{13}{12}\)
\(\dfrac{23}{12}y=\dfrac{13}{12}\)
\(y=\dfrac{13}{12}\div\dfrac{23}{12}=\dfrac{13}{23}\)
Bài 4: Tìm y
a) 100-9:(372:3.y-1)-14=83
b) 7260-120:24.y+924=528.3
c) 2000-52:(615:3:y-15)-14=1984
d) y+y.1/3+5/18=7/18
e) 13/15-(5/21+y).7/12=7/10
h) y+2.y+3.y+4.y+...+10.y=49,5
i) y.(1975/8.9+1885/9.10+1755/10.11+1579/11.12+6=1/24
Tìm y 125*y-12*y-13*y=5.208.000 chi tiết nhất có thể ạ<3
y : 2 + y : 3 + y : 4 = 13
so sánh 52/17 và 120/41
3/4 + 1/4 : ( 7/12 - 1/6 )
372,463 x 998 + 744,926
2- 4 + 6 - 8+ 10 - 12 +........ + 98 - 100 + 102
( y + 112) - 113=79
3/4 - y = 1/2
(4/5 - 2 x y) + 1/6= 5/6
(Y + 1) + ( Y + 2 ) + ( Y + 3)+........+ (Y + 50 ) = 1750
Gỉai giúp t bài này với ạ mơn các c rất nhiều ạ giải chi tiết giùm t với ạ t mơn nhìu ạ
Câu 9. Tìm y, biết:
a) (y – 24) : 28 = 20
b) 13 x (y – 6) = 4 x y - 6
c) y x 3 + y x 4 + y : 3 + y : 4 = 182
Tìm y 125*y-12*y-13*y=5.208.000
tìm y :
a) y + 2 1/3 = 3
b) y - 1 1/4 = 1 1/8
c) 3 - y = 1 1/4
d) y × 2 3/5 = 1 13/15
e) 2 ÷ y = 2 3/7
Gỉai giúp t bai nay vs nhé . Cảm ưn nhìu
so sánh 52/17 và 120/41
3/4 + 1/4 : ( 7/12 - 1/6 )
372,463 x 998 + 744,926
2- 4 + 6 - 8+ 10 - 12 +........ + 98 - 100 + 102
( y + 112) - 113=79
3/4 - y = 1/2
(4/5 - 2 x y) + 1/6= 5/6
(Y + 1) + ( Y + 2 ) + ( Y + 3)+........+ (Y + 50 ) = 1750
Tìm y
a) 3 \(\dfrac{1}{5}\) : 2\(\dfrac{1}{3}\): y = \(\dfrac{12}{7}\)
b) 3 : y x 3 \(\dfrac{1}{2}\)= \(\dfrac{2}{3}x\dfrac{3}{4}\)
c) \(3\dfrac{2}{3}-y+1\dfrac{3}{4}=2\)
