(3xy-0.8)÷y+14.5=15
Dấu . Là phay nha cac bn
3 x X - 0.8 / X -14.5 = 15
3 x X - 0.8 / X -14.5 = 15
Tìm x
( 3 x - 0.8 ) : x + 14.5 = 15
a.\(x+x\cdot\frac{1}{3}:\frac{2}{9}+x:\frac{2}{7}=252\)
b.\(\left(3\cdot x-0.8\right):x+14.5=15\)
2/3*x+3/4=3.giup mik bai toan nay nhe!
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
0.8*y = 1.2 *10
34.8:y=0.8+7.5:15
