For this case we have the following inequations:
1.5x-1> 6.5
7x + 3 <-25
Clearing x from each one we have:
For 1.5x-1> 6.5:
1.5x> 6.5 + 1
1.5x> 7.5
x> 7.5 / 1.5
x> 5
For 7x + 3 <-25:
7x <-25-3
7x <-28
x <-28/7
x <-4
The solution set is:
(inf, -4) U (5, inf)

Step-by-step explanation:
This book doesn't really explain this specific probability question clearly. The circle has 10 small triangles. F is one triangle. We can say that F occurs every 10 small triangles so the ratio would be:
For the second one, we can have D or B, which both have 1 triangle each. We can say that D or B can have 2 triangles out of 10 so the ratio would be:
We can simplify 2/10 to 1/5.
For the third one, we have 3 vowels. So the ratio would be
