The correct answer is 47 dollars and 51 cents.
Answer:
first number=15 second number=6
Step-by-step explanation:
lets take the first and second numbers as "a" and "b"
a-b=9
a+2b=27 (solve these equations simultaneously)
eliminating a
-3b= -18
b= 6
then substitute in the first equation
a-6=9
a=9+6
a=15
I really hope you know how to solve equations simultaneously

Step-by-step explanation:
⇒12)It is an arithmetic sequence.
d=2-1=3-2=4-3=1
a(n) = a +(n-1)d
a(n) = 1+(n-1)1
The next three terms:
a(6) = 1+(6-1)1=6
a(7) = 1+(7-1)1=7
a(8) = 1+(8-1)1=8
⇒13)It is an arithmetic sequence.
d=0-3=-3-0=-6+3=-3
a(n) = a +(n-1)d
a(n) = 3+(n-1)-3
The next three terms:
a(5) = 3+(5-1)-3=-9
a(6) = 3+(6-1)-3=-12
a(7) = 3+(7-1)-3=-15
⇒14)It is <u>not </u>an arithmetic sequence.
⇒15) a(50) = 10 +(50-1)5
=<u>255</u>
