Answer: 12
Step by step explanation:
First simplify both sides of the equation
( 4 )( b ) + ( 4 ) ( - 2 ) + -10 = 2b + 6 (distribute)
4b + -8 + -10 = 2b + 6
(4b) + (-8 + -10 ) = 2b + 6 (combine like terms)
4b + -18 = 2b + 6
4b - 18 = 2b + 6
Then subtract 2b from both sides
4b - 18 - 2b = 2b + 6 - 2b
2b - 18 = 6
After that you add 18 to both sides
2b - 18 + 18 = 6 + 18
2b = 24
2b/2 = 24/2
b = 12

n
=

}
Step-by-step explanation:
We have the sequence
{
−
16
,
4
,
−
1
,
⋯
}
By looking at the first three terms of the sequence, we can already see a pattern.
Starting at -16, each term has its sign reversed, and is divided by 4.
Hence the sequence can be written as:
{
−
16
,
−
16
(
−
1
4
)
,
−
16
(
−
1
4
)
2
,
⋯
}
So the formula for the

Step-by-step explanation:
Average salary = ($65,000 + $72,000 + ... + 88,500 )/5 = $77,100
5% of $77,100 = $3,855
15 years * $3,855/year = $57,825
