[ 1/1Inequality]
Assignment:Find the solution set of inequality (15180-13x)×1000/(5000000-(15180-13x)/1.518) <0.02 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 15180 - 13 * x ) × 1000 / ( 5000000 - ( 15180 - 13 * x ) / 1.518 ) <0.02 (1)
From the definition field of divisor
5000000 - ( 15180 - 13 * x ) / 1.518 ≠ 0 (2 )
From inequality(1):
x > 1160.000101
From inequality(2):
x ∈ R (R为全体实数),即在实数范围内,不等式恒成立!
From inequalities (1) and (2)
x > 1160.000101 (3)
The final solution set is :
x > 1160.000101Your problem has not been solved here? Please take a look at the hot problems !
