c - we want to look for greater than 12 as well as less than.
Answer:

Step-by-step explanation:

In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.

Simplify.

Add b to both sides.

Simplify.

Multiply everything by 3 to remove the fractions.

Simplify.
2b + 3b = 45
Simplify.
5b = 45
Divide 5 from both sides.
5b ÷ 5 = 45 ÷ 5
Simplify.
b = 9

25% is equal to

. To get 25% of 300, we multiply 300 by either 0.25 or

. This gives us
Let x = 0.25555…
10x=2.555…
9x=2.3
90x=23
x=23/90
Let x = the number of alternative schools.
Therefore, 2x - 4 = 48.
2x -4 +4 = 48 + 4
2x = 52
x = 26
Therefore, there are 26 alternative schools(You could check this answer by substituting x=26 into the equation above.).
