x:0.1-x:4-xx3/4=2.25
X : 0,1 - X : 4 - X x 0,75 = 2.25
Tìm x :
a) x : 0.25 + x : 0.1 = 10.3
b) x * 3 : 7.5 + 42.6 = 51.6
c) 4/7 : x * 3/2 + 1/2 = 13/7
2.25 x 0.5 + 2.25 : 2 + 3.75
Bài 1:
a) Tìm x: 75%* x+3/4*x +x=30
b)tính giá trị bieu thức: 1/2:0.5-1/4:0.25+1/8:0.125-1/10:0.1
22 /5 x 6 / 121 x 11/4 x3/5 x 1/3 x5 /4
Tìm x
X : 0.1 - 9.9 = X x 0.1 + 9.9
tìm x
( x -4 ) x3 + 7 = 240
3 x ( x - 5 ) + 8 x x = 62
4.7 x 10 + 4.5 : 0.1 + 92 x 0.1 x 90
