Answer:
an=12−1.5n
Step-by-step explanation:
The first term is 10.5.
The common difference is ...
9 - 10.5 = -1.5
The n-th term can be described by ...
an = a1 +d(n -1)
an = 10.5 -1.5(n -1) = 10.5 -1.5n +1.5 . . . . eliminate parentheses
an = 12 -1.5n

Explanation:
Answer:
x = 3.391
Step-by-step explanation:
first you calculate.
7.9% - 0.25 = 3.22 + x
divide the numbers
- 0.25 = 3.22 + x
calculate again.
0.079 - 0.25 = 3.22 + x
move the terms
<u>-0.171</u> = <u>3.22 + x</u>
add the numbers
<u>-x = 3.22 + 0.171</u>
then change the signs
<u>-x = 3.391</u>
Final ans : <u>x = -3.391</u>
or some alternate answer's
x = -
, x = -3
