A. 60 people exercise regularly (13 + 47).
60 is 100(60 / 250) = 24% of people.
b. 65 people smoke (13 + 52).
65 is 100(65 / 250) = 26% of people.
Answer: 
Step-by-step explanation:
Decompose the denominator.
So, 3 has to be multiplied by p-1 and p+1 has to be multiplied by 1.
Answer: -10
Step-by-step explanation:
Simplifying
-3(y + 5) = 15
Reorder the terms:
-3(5 + y) = 15
(5 * -3 + y * -3) = 15
(-15 + -3y) = 15
Solving
-15 + -3y = 15
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + -3y = 15 + 15
Combine like terms: -15 + 15 = 0
0 + -3y = 15 + 15
-3y = 15 + 15
Combine like terms: 15 + 15 = 30
-3y = 30
Divide each side by '-3'.
y = -10
