Mathematics

Answer:

p =11, q = 3

Step-by-step explanation:

p-q=8

2p-q =19

Multiply the first equation by -1

-p+q = -8

Add this to the second equation

-p+q = -8

2p-q =19

------------------

p = 11

Now we can find q

p -q = 8

11 -q = 8

Subtract 11 from each side

11-11-q = 8-11

-q = -3

q =3

Answer:

? = -36

Step-by-step explanation:

When you raise an exponent to an exponent, the resulting power is a product of the two exponents.

For this problem, you can solve for the missing value by writing:

?*1/3=-12

Divide both sides by 1/3 to isolate the missing value.

?=\frac{-12}{1/3}

Solve for ?.

?=-36
