Answer:


So then Mark purchased 12 Hamburgers and 6 packages of buns
Step-by-step explanation:
For this case we can define the following notation:
B represent the number of packages buns
H represent the number of hamburgers
And from the information given we can set up the conditions into the following equations:
(1) represent the total cost
(2) represent the total number of items
Solving H from equation (2) we got:
(3)
And replacing equation (3) into equation (1) we got:

And dsitributing the terms we have:

And solving for B we got:

And dividing by 5.25 we got:

And replacing the value of B into equation (3) we got:

Answer:
Step-by-step explanation:
hey i think its A)2/3
[(m^(-2/3) n^(3/4)]^3
= m^(-2/3 * 3) n^(3/4 * 3)
= m^-2 n^(9/4)
= n^(9/4) / m^2
answer is C.
n^9/4
--------
m^2
Answer:
It is right
Step-by-step explanation:
square all sides
we have 16, 32, 48
add the two shortest sides, which equal the third side
the triangle works with the pythagorean theorem, so of course it is right :)
