Answer:
The answer to your question is: # of times = 60.7
Step-by-step explanation:
data
7.4 billion people
each person occupied 13 inches
Earth circumference = 25000 miles
length of the lines = 13 in x 7.4 billion people
= 13 x 7 400 000 000
= 9.62 x 10 ¹⁰ in
Convert in to miles
1 mile --------------- 63360 in
x mi --------------- 9.62 x 10 ¹⁰ in
x = 1518308.1 mi
Now divide, the line of people by the circumference
# of times = 1518308.1 mi / 25000 mi = 60.7
The equation is
5x - 13 = 3x + 21
when solved, we get
x = 17
