Hello!
To solve, we want to isolate the x on one side of the equation. We can use inverse operations to put numbers on the other side to find x.
First we undistribute our parentheses.
12x-66+15=21
We subtract 15 from both sides (it cancels out the 15 on the left side, making it 0).
12x-66=6
Now we add 66 to both sides, as -66+66=0
12x=72
Finally, we divide both sides by 12.
x=6
I hope this helps!

Answer:
$74.75
Step-by-step explanation:
When it comes to tax, the sales tax is applied <em>after</em> the discount is provided by the store, as long as it is something like a direct store coupon or a discounted price. In this case, it is a discounted price by the store, so we will include sales tax after.
$79.20 after a 12% discount becomes $69.70 (or $69.696).
The state tax applies to this new price.
7.25% of $69.70 is $74.75
Your answer would be 35 because whatever the angle is that is what the arc length would be.
