12/15 = 400/500
500 people took the survey.
Regrouping is only done into lower place values. For example, tens to ones and hundreds to tens.
P - q = 8.....multiply by -1
2p - q = 19
----------------
-p + q = -8 (result of multiplying by -1)
2p - q = 19
---------------add
p = 11
now we sub 11 in for p in either of the original equations to find q
p - q = 8
11 - q = 8
11 - 8 = q
3 = q
so ur solution is (11,3)
Answer:
5^8
----------- which is choice A
4^4
Step-by-step explanation:
(5^2/4)^4
We can separate this (a/b) ^c = a^c / b^c
5^2^5
-------------
4^4
We know that a^b^c = a^(b*c)
5^(2*4)
------------
4^4
5^8
-----------
4^4
