Answer:

d)  1

Step-by-step explanation:

3a = –2b – 7

We have the point (a, -5) so b = -5

Substituting in

3a = -2(-5) -7

3a = 10-7

3a = 3

Divide each side by 3

3a/3 = 3/3

a =1

There are 12 paperback mysteries on a shelf. This is 40% of the books on the shelf.
hjlf

Answer:

There are 30 books in the shelf.

Step-by-step explanation:

To solve this problem we can use a rule of three in such a way that 12 paperback mysteries are related to 40% of the books in the shelf in the same proportion that "x" total books are related to 100% of the books in the shelf. So we have:

12 -> 40%

x -> 100%

40*x = 12*100

40*x = 1200

x = 1200/40

x = 30 books

There are 30 books in the shelf.
