y x 6+y x 1/3=1/2
y x(6+1/3)=1/2
y x19/3=1/2
y=3/38
\(\frac{y}{24}=\frac{5}{9}\)
\(\Rightarrow y=\frac{5\times24}{9}\)
\(\Rightarrow y=\frac{40}{3}\)
y x 6+y x 1/3=1/2
y x(6+1/3)=1/2
y x19/3=1/2
y=3/38
\(\frac{y}{24}=\frac{5}{9}\)
\(\Rightarrow y=\frac{5\times24}{9}\)
\(\Rightarrow y=\frac{40}{3}\)
tìm y:
a) y x 6 + y : 3= \(\dfrac{1}{2}\)
b)\(\dfrac{y}{24}\)=\(\dfrac{5}{9}\)
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
1)tính nhanh:
1,4 x 26 x 5,6
2) tìm y:
a) y/24 : 8/3 = 3/5
b) 42/25: y/5 = 6/5
Tìm y
y + y x 1/3 : 2/9 + y : 2/7 = 25
y : 4 + y : 3 + y = 5/6
y x 5 + y x 3 + y + y =50
a,6/15=8/y
b,x/5=6/10
c,2/3=12/x
d,24/26=x/12
e,14/56=1/x
g,x/125=2/2
h,6+x/33=7/11
i,5/7=y/147
k,5/7=y/147
l,4/x=y/21=28/49
m,3*x-5/60=2/3
n,2/3*x=3*9
o,24/120=x/5
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: biết : 9/4 - y x 5/6 = 1/2 + 1/3
Tìm các số x, y, x biết rằng :
a) 3x = 2y, 7y = 5z, x - y + z = 32
b) x/3 = y/4, y/2 = x/5, 2x -3y + z = 6
c) 2x/3 = 3y/4 = 4z/5 và x + y + z = 49
d) x - 1/2 = y - 2/3 = z - 3/4 và 2x + 3y - z =50
e) x/2 = y/3 = z/5 và xyz = 810
Các bạn giúp mình nha!
Tìm X và Y:
1. 1/2 + 1/6 x X = 9/2
2. 10/3 - 2/5 : Y = 2/7
3. 32/5 - Y : 2/3 = 1/2
4. 1/5 + 1/7 x Y = 9/8
