Question

x－0．37＋1．63＝2．88

Answer 1

x－0．37＋1．63＝2．88

x－0．37＋1．63＝2．88
解：
x－0．37＋1．63＝2．88
x+1.26=2.88
x=1.62

2.88x=(x+20)X(2.88-0.64)怎么解啊

2.88x=(x+20)X(2.88-0.64)
2.88x=2.24x+2.24*20
0.64x=2.24*20
x=70

()x()=2.88

1.44×2=2.88
0.72×4=2.88
0.36×8=2.88
0.18×16=2.88
0.09×32=2.88
0.03×96=2.88
0.01×288=2.88

1.63x7.6+0.163x2.5-1.63

1.63X7.6+0.163X25-1.63
=1.63X(7.6+2.5-1)
=1.63X10
=16.3

0.24×（7-x）=2.88

0.24×（7-x）=2.88
解7-x=2.88÷0.24
7-X=12
X=7+12
X=19

0.75x-0.34=2.88

0.75x-0.34=2.88
0.75x=3.22
x=322/75

24x-8x=2.88

24x-8x=2.88
16X=2.88
X=2.88÷16
X=0.18

x-0.37x =0.126

1x-0.37x=0.126 (1-0.37)x=0.126 0.63x=0.126 x=0.2

x-0.37x=5.04

x-0.37x=5.04 0.63x=5.04 63x=504 x=8

0.24×3×（7－X）＝2.88

0.24×3×（7－X）＝2.88
解：0.72×（7-X）=2.88
0.72×7-0.72X=2.88
5.04-0.72X=2.88
0.72X=5.04-2.88
X=2.16/0.72
X=3
