<em>Answer:</em>
<em><u>X = 80</u></em>
<em>Step-by-step explanation:</em>
<em>Subtract </em><em>"5"</em><em> from both sides,</em>
<em>3x + 5 - 5 = 245 - 5</em>
<em><u>Simplify,</u></em>
<em>3x = 240</em>
<em><u>Divide both sides by </u></em><em><u>"3"</u></em><em><u>,</u></em>
<em>3x/3 = 240/3</em>
<em>X = </em><em>80</em>

A circle with a radius of 3 cm sits inside of a circle with a radius of 5 cm. What is the area of the Shaded Region?
The shaded region is the area outside the smaller circle and inside the larger circle
we know that
The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle
Remember that
The area of the circle is equal to
so
The area of the shaded region is
![A=\pi [r_1^2-r_2^2]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Br_1%5E2-r_2%5E2%5D)
where
substitute
![A=\pi [5^2-3^2]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B5%5E2-3%5E2%5D)
![A=\pi [16]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B16%5D)
assume
substitute
To find the answer first we will multiply to see how much the books cost. Then we will subtract 50 by the amount of money she has to pay. Then we will check our work to makes sure we are %100 right. Lets do it:-
Lets multiply:-
10 × 2 = 20
So, 10 books cost 20m.
Lets subtract:-
50 - 20 = 30
So she gets 30m in chage.
CHECK OUR WORK:-
30 + 20 = 50
We were RIGHT!!!
So, Coley would receive 30m (B) 30m) in change is she pays with a 50 dollar bill.
Hope I helped ya!!
