Well, since we know is a geometric sequence, we can always get the common ratio of it by simply dividing one value by the one behind it... so let's do so, with say hmm -32 and 8 -32/8 = -4 <-- our common ratio
the first term is -2
Well, you can't really determine the price of 1 book, but you can find out the average cost.
280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x
So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!
Answer:
5x + 27
Step-by-step explanation:
This is because the 5 shirts for x dollars = 5x.
Then 3 shirts cost 9 dollars = 27.
So, the answer is 5x + 27
Answer:
Step-by-step explanation:
Let y = m∠Y.
Then 90 - y = the complement of ∠Y
And 3(90 - y) = three times the complement of ∠Y
And 3(90 - y) + 6 = six more than three times the complement of ∠Y.
