1) 2x + 9 = 2x -5
9 ≠ -5 ; No solution
2) 2x- 1 = x + 3
x = 4; One solution x = 4
3) x + 2 = x + 2
0 = 0; Identity (or all real numbers)

Answer:
The area of the circle is 
Step-by-step explanation:
we know that
The area of a circle subtends a central angle of 
radians
so
By proportion find the area of the circle
You have to distribute!
6(x) = 6x and 6(-6)=-36
So now you have 6x-36=-3(-x+3)
Now do the same on the other side.
-3(-x)=3x -3(3)=-9
So now, 6x-36=3x-9
Combine the like terms:
Subtract 3x in both sides.
6x-3x=3x
Now: 3x-36=-9
Add 36 in both sides.
3x=27
Divide by 3 on both sides to get x alone.
3x/3= x 27/3=9
X=9
Answer: $4.52
Step-by-step explanation:
From the question, sales tax rate is $8.25 per $100, this means that for every $100 item sold, $8.25 will be paid as sales tax.
Sales tax for 54.80 = x
Step 2: write the equation as;
8.25 = $100
Sales tax for $1 item will be (divide both sides by 100
$8. 25/ 100 = $0.0825
Step 3: determine the sales tax on $1 item, that is if sales tax $1 item = $0.0825
Sales tax for $54.80 item will be 0.0825 x 54.80
= $4.52
