Answer:

Hence, the system of equations that is used to represent the situation is:

23x+7y=94-----(1)

16x+14y=38------(2)

Step-by-step explanation:

Let x represent the amount of points received for a correct answer and y represent the amount of points for an incorrect answer.

You’ve gotten 23 questions correct and only 7 wrong,giving you a total score of 94 points.

So, the equation formed is:

23x+7y=94

Your friend, on the other hand, got 16 questions correct and 14 wrong for a total score of 38 points.

So, the equation formed is:

16x+14y=38

Hence, the system of equations that is used to represent the situation is:

23x+7y=94-----(1)

16x+14y=38------(2)

<u>Answer:</u>

The correct answer option is d. 9.

<u>Step-by-step explanation:</u>

We are given an expression $27^{\frac{2}{3} }$ and we are supposed to simplify it.

We can also write $27^{\frac{2}{3} }$ as $(3^3)^{\frac{2}{3} }$ .

We know the power rule $(a^m)^n=a^{mn}$ which means that to raise a power to a power you need to multiply the exponents.

So multiplying the exponents to get:

$(3^3)^{\frac{2}{3} }\\3^{3.\frac{2}{3}$

3 gets cancelled by 3 so we are left with:

$3^2$ $=9$

Therefore, the correct answer option is d. 9.
