x > what number?

12 + 5x > 2(8x - 6) - 7x

12 + 5x > 16x - 12 - 7x

5x - 16x + 7x > -12 - 12

-4x > -24 / : (-4)

x < 6

12 + 5x > 2(8x - 6) - 7x

12 + 5x > 16x - 12 - 7x

5x - 16x + 7x > -12 - 12

-4x > -24 / : (-4)

Given the circumference of a circle is 26 pi, what is the area of the circle? Show work. Leave answer in term of pi.

Step-by-step explanation:

Circumference(c)=26pi

26pi=2pi x r

Divide both sides by 2pi

26pi/2pi=(2pi x r)/2pi

13=r

Area of circle=pi x r^2

area of circle=pi x 13^2

Area of circle=169pi
