Answer:

The correct answer option is d. 9.

Step-by-step explanation:

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.

If point a is located at (-7,-3) and there are 12 points between a and b what could be the possible cordinates for point b

KonstantinChe [14]

Answer:

(-19,-3) or (5, -3)

Step-by-step explanation:

If b is located to the left side of a, then we need to add (-12) to the x-coordinate of a

b(-7+ [-12],-3) = b(-19,-3)

If b is located to the right side of a , then we need to add 12 to the x-coordinate of a.

b( -7+ 12, -3)= b(5 , -3)

keiko david and tony have a total of 106$ in their wallets. david has $6 less than keiko tony has 2 times what david has. how mu

mafiozo [28]

<h3>Answer:</h3>

Keiko have $31 in her wallet.

David have $25 in his wallet.

Tony have $50 in his wallet.

<h3>Step-by-step explanation:</h3>

Keiko

Let x = the amount in Keiko’s wallet.

David

David has $6 less than Keiko .

x - 6

Tony

Tony has has two times what David has.

2(x - 6)

The total sum of their money = 106

Keiko

x + x - 6 + 2(x - 6) = 106

2x - 6 + 2x - 12 = 106

4x - 18 = 106

4x = 106 + 18

4x /4 = 124/4

x = 31

Therefore Keiko have $31 in her wallet.

David

x - 6

31 - 6 = 25

Therefore David have $25 in his wallet.

Tony

2(x - 6)

2(31 - 6)

2(25) = 50

Therefore Tony have $50 in his wallet.

To check your work out

31 + 25 + 50 = 106
