We have to consider the Order of Operations
And Divide the question into different parts
So we first do the Exponent: 2^{5} = 32
(3×32-26)=(96-26)=70
Solve the parts in parenthesis 
(8-(4-9)=(8-(-5)=(8+5)=13 (minus and minus becomes addition)
Distribute 7
7(13)=91
Now put the equation and equate everything
(3×2^{5}+13(-2))+7(8-(4-9)=70+91=161
Final Answer=161

PLEASE HELP!!!!! "A country's population in 1991 was 70 million. In 1998 it was 74 million. Estimate the population in 2010 usin
Blizzard [7]

Answer:

81 million

Step-by-step explanation:

A = Pe^rt

Let's break this equation down.

A is the total you will have.

P is the starting value.

R is the rate

T is the time.

Let's find the rate first.

74000000 = 70000000e^7r

Divide each side by 70mil

74000000/70000000 = e^7r

Then take the ln() of each side.

ln(74000000/70000000) = 7r

0.0556 = 7r

r = 0.0079

Now we can find how many people will be there in 2010.

A = 70,000,000e^(19 * 0.0079)

A = 81336530.2373

Now we round to the nearest million, leaving us with 81 million.
