This is a system of equations problem that can be solved using one of three methods: <span>graphing, substitution, or <span>elimination. I'll be using substitution.
In substitution:
1) S</span></span><span>olve one equation for either variable. I'll use the first equation because its easier to solve for one of the variables. I'll be solving for y because that will allow us to solve for the value of x faster.
</span>


2) Substitute what you get into the other equation:


3) Solve your new equation in step 2 for the variable, x.




There are
D) 20 $20 bills in her drawer.
Answer:
9π
Step-by-step explanation:
The area of the square is 36 so the side length is 6 because
=6 so
the diameter of the circle is 6 and the radius is 3
the area of a circle is πr² so
3²π=
9π
I think that it would be B i think
