Answer: x = 6 .
_________________________________
Explanation:
____________________________________________________
 Given: 9x + 3 = 57 ; Solve for "x" ;
___________________________________
Subtract "3" from EACH side of the equation:
_________________________________________
9x + 3 − 3 = 57 − 3 ;
_________________________________________
to get:
_________________________________________
9x = 54 ;
__________________________________________
Now, divide EACH side of the question by "9" ; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________________
9x / 9 = 54 / 9 ;
____________________________________________
x = 6 .

Round to the nearest hundredth if so. Use 3.14 as pi 8. r= d = C=78.8 ft

Kryger [21]

Answer: The radius is 12.54 feet, and the diameter is 25.08 feet.

Explanation: By applying the circumference into the equation r = $\frac{C}{2\pi }$ , we get r = $\frac{78.8}{2\pi }$ which simplifies the radius. And since radius is half of diameter, we multiply by 2 to get the diameter as well to solve the other blank in the problem.

Hope this helps! :D
