B
Step-by-step explanation
the answer comes to 
and 15 is the only answer below 20
Given the equation, S = D/T:
To make the D the subject of the equation, we can start by multiplying both sides by T to isolate D:
(T) S = D/T (T)
TS = D
Therefore, the final answer is D = TS
Angle 1 and 2 are vertical angles
Hope this helps :)
the factor for this expression is 7
To get 1/10 -> 1000/10 =100
and 1% of 100 -> 100/100 = 1 or 1%
100 for question 1
1 for q2
