The solution for the compound inequality is 
Explanation:
The equations are
and 
To find the solution set for these compound inequalities, we need to solve the inequality.
First, we shall solve the inequality 
Adding both sides of the equation by 10, we have,

Dividing both sides by 3.5, we get,

Now, we shall solve the inequality
,
Adding both sides of the equation by 9, we have,

Dividing both sides by 8, we get,

Thus, the solution set for the inequalities
and
is
