Bảo Ngân k tớ nhé
\(48,47-x+8,6=10,1\)
\(39,87-x=10,1\)
\(x=39,87-10,1\)
\(x=29,77\)
vậy.........
\(x:10+3,9x=4,8\)
\(\left(\frac{1}{10}+3,9\right)x=4,8\)
\(4x=4,8\)
\(x=1,2\)
vậy \(x=1,2\)
48,47 - x + 8,6 = 10,1
48,47-x=10,1-8,6
48,47-x=1,5
x=48,47-1,5
x=46,97
x : 10 + x × 3,9 = 4,8
x.1/10+x.3,9=4,8
x.(1/10+3,9)=4,8
x.4=4,8
x=4,8:4
x=1,2
k mk nhé
1 ) 48,47 - x + 8,6 = 10,1
48,47 - x = 10,1 - 8,6
48, 47 - x = 1,5
x = 48,47 - 1,5
x = 46,97
\(\text{48,47-x+8,6=10,1}\)
\(48,47-x=10,1-8,6\)
\(48,47-x=1,5\)
\(x=48,47-1,5\)
\(x=2,97\)
\(x:10+x.3,9=4,8\)
\(x.0,1+x.3,9=4,8\)
\(x.\left(0,1+3,9\right)=4,8\)
\(x.4=4,8\)
\(x=4,8:4=1,2\)
a) 48.47-x+8.6=10.1
48.47-x =10.1-8.6
48.47-x =1.5
x =48.47-1.5
x =46.97
b)x : 10 + x * 3.9 =4.8
x* 1/10 + x * 3.9 = 4.8
x* (1/10 + 3.9 ) = 4.8
x* (0.1 + 3.9 ) =4.8
x* 4 =4.8
x = 4.8 : 4
x = 1.2
