1. Rewrite the system:
x+12y=68 (i)
x=8y-12 (ii)
2. Let's substitute the equation (ii) into the equation (i):
x+12y=68
(8y-12)+12y=68
3. Then, you have:
8y-12+12y=68
4. When you clear "y", you have:
20y-12=68
20y=68+12
20y=80
y=80/20
y=4
5. You already have the value of "y". Now, you must substitute this value into the equation (ii):
x=8y-12
x=8(4)-12
x=32-12
x=20
6. Therefore, the result is:
x=20
y=4
The circumference<span> of a circle is the distance around the circle. </span>The circumference of a circle is calculated by the expression:
Circumference = 2πr
Circumference = 2π(30 inches)
Circumference = <span>94.2 inches
</span>
Therefore, the correct answer from the choices listed above is option C. Hope this answers the question.
