6. The public library has volunteers shelve books after they have been returned. When Lisa arrives to volunteer, there are 5 non-fiction books for
every 9 fiction books. If there are 117 fiction books to shelve, then how
many non-fiction books need to be shelved?

2nd one in the first row is correct

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
