Answer:
A.) Kathy starts each week with 108 phones to fix.
The formula to find the circumference of a circle is C=2*pi*r.
Substitute 9 1/4 or 9.25 for r.
C=2*pi*r
C=2*pi*9.25
C=18.5pi
The circumference of the circle would be 18.5pi.
<h2>Answer: 297</h2>
<h3>Step-by-step explanation:</h3>
Based on the 4 terms given in the sequence, we can determine the rule to be: 6n - 3
1s term: 6(1) - 3 = 3
2nd: 6(2) - 3 = 9
3rd: 6(3) - 3 = 15
4th: 6(4) - 3 = 21
<h3> ∴ 50th term = 6(50) - 3 = 297</h3>
Given:

First, let's move the -1 to the right side. When we add
, we get
.

Now we can cross multiply, multiply (3n)(8) and (7)(9)

Simplify the left side.

Simplify the right side.

Divide both sides by 24 to isolate n.

Simplify.
