X= ( 6 3/5 : 6 - 0.125 x 8 + 2 2/15 x 0.03) x 11/4
1) tìm x biết:
x= (6và 3/5 : 6 - 0.125 x 8 + 2 và 2/5 x 0.03)x 11/4
TÌM X ,BIẾT:X:6x7,2+1,3xX+X:2+15=19,95
Tính nhanh:
\(25\%+\dfrac{3}{4}+\dfrac{1}{2}:0.5-\dfrac{1}{4}:0.25+\dfrac{1}{8}:0.125\)
Bài6:Tìm x
a,x+1/4-3/8=7/12
b,x-3/14=5/14+15/21
c,3/10:x=1/10-1/20
d,x:8/25=1/2×4/5
tìm x biết:x-1+x-3+x-5+x-7+....+x-201=202
tìm x
a) X-2/7=1/5
b) 15/8-X=3/2
c) X x 7/5=7/20
d) 18/25 : X=9/5
Tìm X, biết:
X + (X + 1) + (X + 2) + (X + 3) + ...+ (X + 19) = 950
7/2 + 2/25
