Answer: x=18
Step-by-step explanation:
First distribute:
(18/6)-(x/6)=0
Isolate the x variable:
(18/6)=(x/6)
18=x
The radius of the sector is 10.27 miles
<h3>How to find the radius of a sector?</h3>
The area of a sector can be represented as follows;
area of a sector = ∅ / 360 × πr²
where
- r = radius
- ∅ = central angle
Therefore,
∅= 25 degrees
area of the sector = 23 miles²
area of a sector = ∅ / 360 × πr²
23 = 25 / 360 × πr²
cross multiply
23 × 360 = 25πr²
8280 = 25πr²
divide both sides by 25
πr² = 8280 / 25
πr² = 331.2
r² = 331.2 / 3.14
r² = 105.477707006
r = √105.477707006
r = 10.2702336877 miles
Therefore, the radius of the sector is 10.27 miles

Answer:
C. 3 3/4
Step-by-step explanation:
Answer:
12-9x
Step-by-step explanation:
Here, we want to write an algebraic expression from the given statement
Let us start with the product of 9 and a number x
What this mean is that we want to multiply 9 and x
That gives 9 * x = 9x
Now, 12 is decreased by this product means we are to subtract 12 from it
we have this finally as;
12-9x
