Answer:
4 books
Step-by-step explanation:
D, hope this helps because 1/2 is less than 1. and 5*1/2 is 2.5 and that is less than 5
The perimeter would be 48 feet
B={x|x is an even whole no less than 9}
Now

3x + 4y = 16 Write original equation
3x + 4y - 4y = -4y + 16 Subtract 4y from each side
3x = -4y +16 Simplify
3x/3 = -4y/3 + 16/3 Divide each side by three
x = -4y/3 +16/3 Simplify
I hope this helps!
