Answer:
x > -1
Step-by-step explanation:
-3x +8 < 11
Subtract 8 from each side
-3x +8-8 < 11-8
-3x < 3
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 3/-3
x > -1
<span>32 cm wide by 25 cm tall.
Since each photo is square and has an area of 25 cm², that means that the length of each edge of the photos is 5 cm. So the length of a page (2 border gaps + 4 photos + 3 spacing gaps) is
2*3 + 4*5 + 3*2 = 32 cm
The height of a page (2 border gaps + 3 photos + 2 spacing gaps) is
2*3 + 3*5 + 2*2 = 25 cm
So the page size is 32 cm x 25 cm</span>
Answer:

Step-by-step explanation:
We are given the following in the question:
Percentage of students who choose Western riding = 35%

Percentage of students who choose dressage= 45%

Percentage of students who choose jumping = 50%

Percentage of students who choose both dressage and jumping = 20%

Percentage of students who choose Western and dressage = 10%

Percentage of students who choose Western and jumping = 0%

Thus, we can say

Formula:

a) P(student chooses dressage or jumping)

b) P(student chooses neither dressage nor Western riding)
