ANSWER

The correct answer is C x=3.



<u>EXPLANATION</u>


We have

4x+2y=12---(1)


and


x-y=3---(2).


We solve the two equation simultaneously by elimination method. We need to be smart and eliminate y, since we are looking for x.



We first multiply equation (2) by 2

2x-2y=6---(3).


We add equation (3) and (1).


\Rightarrow 6x=18.

Dividing through by 6 gives

x=3.

jeka57 [31]

Answer:

Monthly payment = $18325.6

Step-by-step explanation:

From the question,

P = 14000

t = 4 years

R = 6.75%

To calculate the monthly payment for this loan, let's use the below formula

Amount = P( 1 + 6.75%/12)^4×12

Amount = 14000(1.005625)^48

Amount = 18325.633 dollars

Monthly payment = $18325.6

National Income (NI) is the sum of the incomes that all individuals in an economy earn in the forms of wages,
Dennis_Churaev [7]

Answer:

\simeq 14.94  billion dollars

Step-by-step explanation:

During the period 1994 - 2004, the 'National Income' ,(NI) of Australia grew about 5.2% per year (measured in 2003 U. S, dollars).  In 1994 , the NI of Australia was $ 4 billion.

Now,

(2020 - 1994) = 26

Assuming this rate of growth continues, the NI of Australia in the year 2020 (in billion dollars) will be,

4 \times[\frac{(100 + 5.2)}{100}}]^{26}

=4 \times[\frac{105.2}{100}]^{26}

=\simeq 14.94  billion dollars (answer)
