How to find the diameter of a circle with the area of 1134.1?

Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?
zavuch27 [327]

Answer:

x = 2

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?

13x - 2(8 + 5x) = 12 - 11x

<u>Step 2:  Distribute</u>

13x - 2(8 + 5x) = 12 - 11x

13x - 16 - 10x = 12 - 11x

<u>Step 3:  Solve for x</u>

13x - 16 - 10x + 11x + 16 = 12 - 11x + 11x + 16

14x / 14 = 28 / 14

x = 2

Answer:  x = 2

Given the system of linear equations:
Vanyuwa [196]

Answer:

Step-by-step explanation:

hello :

Part A :  x+6y =6 means : 6y = - x+6

so : y = (-1/6)x+1  an equation for the line (D)

     y = (1/3)x -2 is the line (D')

PartB : solution of the system  : y = (-1/6)x+1 ....(1)    color  red

                                        y =  (1/3)x -2 ....(2)  color  bleu

is the intersection point : (6 ; 0)

PartC : Algebraically  by (1) and (2) : (-1/6)x+1 =  (1/3)x -2

(-1/6)x  - (1/3)x = -2-1

(-x-2x)/6= -3

-3x = -18

so : x = 6  put this value in (1) or (2) : y = (-1/6)(6)+1 =0 the solution is : (6 ;0)
