Answer:
m = 9
It means that you are multiplying each of the values inside the parentheses by 2.
Step-by-step explanation:
2(m + 2) = 22
2m + 4 = 22
2m + 4 - 4 = 22 - 4
2m = 18 -Divide both sides by 2
m = 9

Step-by-step explanation:
Answer:
2010.
Step-by-step explanation:
We have been given an exponential growth formula
, which represents number of passengers traveling by airplane since 1990.
To find the year in which 900 million passengers will travel by airline, we will equate the given formula by 900 and solve for t as:



Take natural log of both sides:

Using property
, we will get:




This means that in the 20th year since 1990, 900 million passengers would travel by airline.

Therefore, 900 million passengers would travel by airline in 2010.
Answer:
Step-by-step explanation:
5p + 9c = p
9c = p - 5p
9c = -4p
c = -4p/9
c=
