This is a geometric sequence with a common ratio of -1/3 and an initial term of -324. Any geometric sequence can be expressed as:
a(n)=ar^(n-1), in this case a=-324 and r=-1/3 so
a(n)=-324(-1/3)^(n-1) so the 5th term will be
a(5)=-324(-1/3)^4
a(5)=-324/81
a(5)= -4
Hello,
x = The number of cans of paint.
y = number of brushes.
25x + 12.75y = 327
Thanks,

Step-by-step explanation:
Is it possible for Bruce and Felicia to have used the same number of tiles? Use complete sentences to explain your reasoning.
No
5x + 2 ≠ 5x + 5
because
2 ≠ 5
If they each used the same number of tiles, how many tiles were in each box?
6x + 2 = 5x + 17
6x - 5x + 2 - 2 = 5x - 5x + 17 - 2
x = 15 tiles
