Answer:
5 newspapers in 1 pile
Step-by-step explanation:
If there are 10 newspapers in 2 piles, to find the number of newspapers in 1 pile, we need to divide 10÷2 which equals 5.
Answer:
5
Step-by-step explanation:
3(2x-5)-2=x+8
6x-15-2=x+8
6x-17=x+8
6x-x-17=8
5x-17=8
5x=8+17
5x=25
x=25/5
x=5
Based on the calculations, all of the numbers belong to this arithmetic sequence.
<h3>How to calculate an arithmetic sequence?</h3>
Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:

<u>Where:</u>
- d is the common difference.
- a₁ is the first term of an arithmetic sequence.
- n is the total number of terms.
Next, we would determine the common difference as follows:
d = a₂ - a₁
d = 105 - 99 = 6.
d = a₃ - a₂
d = 111 - 105 = 6.
d = a₄ - a₃
d = 117 - 111 = 6.
Based on the calculations, all of the numbers belong to this arithmetic sequence.

Answer:
Step-by-step explanation:
Her former rent is $ x
Twice the former rent: 2*x = 2x
$300 less than 2x: 2x - 300
2x - 300 = 550
Add 300 to both sides
2x - 300 + 300 = 550 + 300
2x = 850
Divide both sides by 2
2x/2 = 850/2
x = 425
Her former rent = $425
