Let's let x equal the original price of the dress.
We know that 16.6666% is equal to 0.16666 in decimal form by dividing the percent by 100.
So we can set up the equation:

because we know the discount, and we know that the discount of the original price was subtracted from the original price.
So then let's simplify by taking out x, the common factor:

Then solve for x:



So now we know that the original price of the dress was $39.
Answer:
y=9sin(theta)
Step-by-step explanation:
I'm assuming it's in degrees. The amplitude of the graph is 9, and so you multiply the base sine equation y=sin(theta) by nine. I don't see any shifts and the period remains at 2pi (360 degrees) so I don't think anything else is really needed.
Answer:
Step-by-step explanation:
<A = 5x + 34
and
<B= 2x +76
Since <A and <B are equal
then
5x + 34=2x +76
5x - 2x = 76 - 34
3x = 42
x = 42/3
x = 14 degrees
Now, <A = 5x + 34
<A = 5(14) + 34
< A = 104 degrees
Also,
< B = 104 degrees
Answer:
0.25 I'm pretty sure I hope this helps
