(x-45)/(x-24)=62.5%,怎么算
(x-45)/(x-24)=62.5%,怎么算
(x-45)/(x-24)=62.5%,怎么算
两边乘以x-24
x-45=0.625(x-24)
x-45=0.625x-15
x-0.625x=45-15
0.375x=30
x=30÷0.375
x=80
X-45=0.625X-15
0.375X=30
X=80
擦,题目看错,无视。。
(X-45)/(X-24)=62.5%
(X-45)/(X-24)=5/8
(X-45)×8 =(X-24)×5
8X -360 =5X -120
3X =240
X=80
去分母,去括号,得x=80
(x-45)*100=(x-24)*62.5
625x-15000=1000x-45000
375x=30000
x=80
求x-45=(x-24)*80%错了,是x-45=(x-24)*62.5%
(x-45)/(x-24)=62.5%等于多少?
(x-45)/(x-24)=62.5%,怎么算
24-X=62.5%(30-X)
一元二次方程解答!x(5x+4)=5x+44x^2-45=31x-3x^2+22x-24=0(x+8)(x+1)= -12(3x+2)(x+3)=x+14
45-x=1.5(24+x)
(45-x)除以(24+x)=1.5
(X+X)+(X-X)+(X*X)+(X/X)=100
x-20%x=45+20%x
x平方=(24-x)(12-x)
X(X+1)(X+2)=24
x*x+2x=24 ,x=?
X+(X+8)+(X+16)=96X=24
(X^+X)(X^+X-14)+24=0 ^代表平方
x×x--2x=24 x等于多少?
(x+1)(x+2)(x+3)(x+4)=24
2x乘以x乘以x=24,求x!
(x+1)(x+2)(x+3)(x+4)=24
