Answer:


\huge\boxed{\bf\:w = (49)/(2) = 24(1)/(2) = 24.5}

Explanation:


w - 9 \frac { 1 } { 2 } = 15

Multiply both the sides of the equation by 2.


2w-\left(9* 2+1\right)=30 \\2w-\left(18+1\right)=30 \\2w-19=30

Bring
19 to the left hand side of the equation.


2w=30+19 \\2w=49 \\\boxed{\bf\:w = (49)/(2) = 24(1)/(2) = 24.5}

Answer:

Option A

Explanation:

Convert mixed fraction to improper fraction.


\sf w - 9(1)/(2)=15\\\\ w - (19)/(2)=15

Now isolate 'w'


\sf w = 15 +(19)/(2)\\\\= (15*2)/(1*2)+(19)/(2)\\\\=(30)/(2)+(19)/(2)\\\\=(30+19)/(2)\\\\=(49)/(2)\\\\= 24(1)/(2)
