The solution set of the compound inequality 3.5x - 10 > -3 and 8x - 9 < 39 is ?
Solution:
3.5x - 10 > -3 can be written as
(7/2)x > 10 - 3
(7/2)x > 7
x > 2
Similarly
8x - 9 < 39
8x < 48
x < 6
Since x > 2 and x < 6, we can say that the solution of the compound inequality is 2 < x < 6
The solution set of the compound inequality 3.5x - 10 > -3 and 8x - 9 < 39 is ?
Summary:
The solution set of the compound inequality 3.5x - 10 > -3 and 8x - 9 < 39 is 2 < x < 6
