Question

求解数学计算题

(X-65000)/X=0.11，求X=多少，这题有解吗

Answer 1

有啊：
(X-65000)/X=0.11

X-65000=0.11X

X-0.11X=65000
0.89X=65000
X=65000/0.89
X=6500000/89

Answer 2

追答

把x成过去

x=73033

Answer 3

(1)
原式
=(0.25)^23×2^46×2×2
=(0.25)^23×(2^2)^23×4
=(0.25×2^2)^23×4
=1^23×4
=4

(2)
原式
= -8×(-0.125)^2000×(-8)^2000×(-8)
= 64×(-0.125×(-8))^2000
= 64×1^2000
= 64

Answer 4

650分之89把

Answer 5

(X-65000)/X=0.11

X-65000=0.11X (x不等于0)
100X-6500000=11X
X=6500000/89

Answer 6

(X - 65000) / X = 0.11

X- 65000 = 0.11X

0.89X = 65000

X = 73033.71
