All you need to know is that a km is 1000 m ( as the prefix kilo always means 1000 let it be even 1kg and that is equal to 1000g )
also know
that a 100 cm is 1 m and that's cause the prefix centi is 10^–2 (0.01)
answering your question
a) 5km = 5000m
5km and 20m in m is 5000m + 20m = 5020m
b) 13 cm = 13/100m = 0.13m
7m and 12cm is 7m + 0.13m = 7.13m.
remember
1km = 1000m
100cm = 1m

Answer:
this is a question.
Step-by-step explanation:
Since it is a given that the angles are vertical, then that means they have to be congruent or = to each other so we can now set up an equation:
3x+7=x+53
Now we need to get the variable alone on one side so subtract 7 from the left (remember what you do, you must do to both sides)
3x=46
Now we can divide by three to get x alone
x=15.333333333 or rounded to 15.33
