Answer:
y = 6.5
Step-by-step explanation:
Using a ratio
10 13
----- = -----------
10+5 13+y
10 13
----- = -----------
15 13+y
Using cross products
10(13+y) = 13*15
10(13+y) = 195
130+10y = 195
Subtract 130 from each side
10y = 65
Divide by 10
y = 65/10
y = 6.5
Answer:
b(4) = -405
Step-by-step explanation:
The first term of the sequence has been represented by 15.
The common ratio is -3
Since the first term is 15 you would have to multiply by -3 to find the next three terms.
B(1) = 15
B(2) = -45
B(3) = 135
B(4) = -405
The fourth term is -405
Answer:
-405
The unit price would be $0.20 because when you divide $3.20 by 16, that is what you would get. The equation would be

Im guessing its 2 x X x2-y
the answer would be 4
