Let's use q to represent the number of quarts needed.
you would have the following:
2q= 107-19
2q=88
q=44
44 is the number of quarts in a in the barn.
Now you have to divide that number by 4 to get gallons because there is 4 quarts in a gallon.
There are 11 gallons of paint.
a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number
might be confusing so here's an example
1,2,4,8,16
each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio
formula for geometric sequence is

where
is nth term
is first term
r is teh common ratio
n=which term
in our example
1,3, 9, 27, 81
each term is being multiplied by 3 so it is a geometric sequence and thus r=3
also first term is 1 so 
so the formula is
or in function notation 
Answer:
There are many variables to determine if you have all the complete pieces some are the following:
1.- bowl size
2.- the way it broke
3.- the size of the pieces
4.- if the pieces can fit together
5.- if the bowl paint has the same figures
This is important to determine, since if they do not have these requirements, you can find different pieces of different bowls, which will make the pieces never coincide with each other.
Answer:
C. 18
Step-by-step explanation:
4-6 paris = about 23
10-12 pairs = about 5
28 - 5 = 18
