In 2003, the population of an African country was about 23.5 million people, which is 3 million more than 5 times the population in 1950. Enter and solve an equation to find the approximate population p (in millions) in 1950. An equation is . The approximate population in 1950 was million people.

Step-by-step explanation:

An equation is 5p + 2 = 18.5.

The 1950 population was approximately 3.3 million.

Step-by-step explanation:

If p  million was the population in 1950 the equation is:

5p + 2 = 18.5

5p = 16.5

p = 16.5 / 5

p =  3.3 million.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
