What is the value of x in the equation 3x-1/9y=18 when y= 27

Step-by-step explanation:

x =7

Step-by-step explanation:

3x-1/9y=18

Add 1/9 y to each side

3x-1/9y + 1/9 y=18+ 1/9 y

3x = 18 + 1/9 y

Divide by 3

3x/3 = 18/3 + 1/9y *1/3

x = 6 + 1/27 y

Let y = 27

x= 6+ 1/27 * 27

x = 6+1

x = 7

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
