f(n) = -6.5n + 14.5
&
f(1) = 8, f(n+1) = f(n) - 6.5
The answer is 63/1, so basically 63 is your answer.
To show my work all u have to do is divide 378/6 and get 63, divide 6 by 6 and u get 1, simplify it and u get 63. How did I get 6 in the first place? I found the gcf( greatest common factor) of both 378 and 6, then I simplified the fraction by dividing both numerator and denominator and got 6.
Hope this helps and if it does, don't forget to mark as brainliest.
Answer:
Just Transposition...
Step-by-step explanation:
12×7=84=d
92-49=43=e
28+57=85=f
96÷16=6=g
11×8=88=h
95+5-29=100-29=71=I
55-6+21=70=j
88+8÷4=96÷4=16=k
19+24-97=-97-43=54=m
-20+17+61=61+3=64=n
hope it helps
The formula for compound interest is : A = P(1+r/n)^nt
A = 4000 (1+0.021/4)^4x4
A = 4000 (1.021)^16
A = 5,577.91
Sergio's total interest would be : 5,577.91 - 4,000 = $ 1,577.91
hope this helps
