Answer:

- 1, 2, 5, 8, 11

Step-by-step explanation:

Substitute n = 1, 2, 3, 4, 5 into the n th term formula

a₁ = 3(1) - 4 = 3 - 4 = - 1

a₂ = 3(2) - 4 = 6 - 4 = 2

a₃ = 3(3) - 4 = 9 - 4 = 5

a₄ = 3(4) - 4 = 12 - 4 = 8

a₅ = 3(5) - 4 = 15 - 4 = 11

The first 5 terms are - 1, 2, 5, 8, 11

henry rented a truck for one day. there was a base Fee of $18.95, and there was an additional charge of $.79 for each mile drive
crimeas [40]
<h3>Henry drove the truck for 208 miles</h3>

<em><u>Solution:</u></em>

Given that,

Base fee = $ 18.95

Additional charge of $.79 for each mile driven

Let "x" be the miles driven

Henry had to pay $183.27 when he returned the truck

Therefore,

Cost for rent = base fee + charge for "x" miles

183.27 = 18.95 + 0.79x

0.79x = 183.27 - 18.95

0.79x = 164.32

Divide both sides by 0.79

x = 208

Thus Henry drove for 208 miles the truck

A company has the pay scales below , with the percent of employees receiving that pay listed. Find the best value to represent a
LenKa [72]
The given table is the following:

  Job          Salary   % of Employees
--------    ------------   ----------------------
Entry      $30,000      60%
Expert    $40,000      38%
CEO     $125,000        2%

Let n = total number of employees.

Entry:
Number  = 0.6n
Pay total = 0.6n*(30,000) = $18,000n

Expert:
Number = 0.38n
Pay total = 0.38n*(40,000) = $15,200n

CEO:
Number = 0.02n
Pay total = 0.02n*(125,000) = $2,500n

Total pay = 18,000n + 15,200n + 2,500n = $35,700n
Average salary = 35,700/n = $35,700

Answer: $35,700

Answer: Yes

What equation represents the area of a rectangle whose length is x 4 and whose width is x − 9?
Lena [83]
The area of a rectangle is length * width so: (x+4) * (x-9)

(I assumed you meant x+4 just forgot to put the "+" there, if it's something else, then just simply use that instead.)
