Answer:
9 books on each shelf
Step-by-step explanation:
43 + 29 = 72 books total
72/8 = 9 books per shelf
In order to answer that question, we need to know the scale of the map.
Without that information, no answer is possible.
I think you have it in the first part of the question ... the part you decided
not to post.

OK. Now that you've provided the scale of the map,
answering the question is a piece-o-cake.
Use a proportion:
(1 inch on the map) / (4 miles on the ground) = ('x' on the map) / (17 miles on the ground)
Step-by-step explanation:
Given equation of circle is,

again the another form of circle is,

now equating the values of f in both equations,
-k=-3
i.e. k=3
therefore k=3
8.6 because 1 is not great enough to boost that 6 up to a 7
Answer:
Step-by-step explanation:
6j - k = 23
6j + 3k = 11.....multiply by -1
---------------
6j - k = 23
-6j - 3k = -11 (result of multiplying by -1)
---------------
-4k = 12
k = -12/4
k = - 3 <=====
6j - k = 23
6j - (-3) = 23
6j + 3 = 23
6j = 23 - 3
6j = 20
j = 20/6
j = 10/3 <===
solution is : j = 10/3 and k = -3
