Tìm y
24/y : 8/3 = 3/5
42/25 : y/5 = 6/7
Làm ơn giải giúp em, em tick cho
Tìm y:
a) 7 , 25 × y + 5 , 6 = 58
b) 470 , 04 : y = 24
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 x:
a, x + 17, 67 = 100 - 63,2
b, x : 7,5 = 3,7 + 4,1
c, 470 , 04 : x = 24
A, 564271 -134593 =
B, 9/8 - (17/ 3 - 3/7 ) + 7/8 =
C , 12371 - 5428 - 304,29 =
D, 0,25 * 5, 87 * 40 =
E, 7, 48 * 99 + 7,48 =
H , 98 ,45 - 41 ,82 - 35 ,63 =
tìm x
A, x + 3,5 = 4,72 + 2,28
B, x - 7,2 = 3,9 + 2,5
C, 470 ,04 : x = 24
Câu 7: (1 điểm)
a) Tính: 36 giờ 18 phút : 6+58 phút; b) Tìm y : 0,8 x y = 1,12 x 10

a,5/y=1/2 (tìm y)
b,42/25:y/5=6/5(tìm y)
Giup tui vs
Tìm y biết:
a. y – 6 : 2 – ( 48 – 24 x 2 : 6 – 3) = 0
b. (7 x 13 + 8 x 13) : ( 9 2 3 – y) = 39
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:
a) y x 6 + y : 3= \(\dfrac{1}{2}\)
b)\(\dfrac{y}{24}\)=\(\dfrac{5}{9}\)
