1/4(2x+5)³+250=0 的解为
(x-1):12=4.5:5.4 2.5:x=0.2:40% x-9分之4X=250
(1+1X2)/ 250+(3+2X2)/250+(5+2X3)/250+.+(999+2X500)/250
2x-1-x/3=x+2/4-3 1/5(2x-1/3-4)=1 x-0.1/0.3-1.2=x+0.2/0.5 5x+
[4x−1.5/0.5−5x−0.80.2=1.2−x0.1].
急,怎么解 0.5x/0.2 - 1.5-x/2= 0.5 1+x/0.1 - 0.4x-0.5/0.2 = 1/2
(4x-1.5)/0.5-(5x-0.8)/0.2=(1.2-x)/0.1-3
0.5/4x-1.5-0.02/0.5x-0.08=0.1/1.2-x+2
(4X-1.5)/0.5-(0.5X-0.08)/0.02=(1.2-X)/0.1+2
(1)X-1)(1-2x)>0(2)6x²+5x<4(3)-3x²+x+1>0(4)x²-2x+1≤0(5)4x-x²<
