A bulletin board has an area of 1/ 12 yd and a length of 1/3 yard the bulletin board is divided into six equal sections right vision expressions to solve each part and show your work

Step-by-step explanation:

Given:

Area = 1/12 yd^2

Length = 1/3 yd

Area of a rectangle = length × width

Width = 1/12 ÷ 1/3

= 1/4

Since it is divided into 6 parts, it can be written as 2 × 3 pattern.

Since the length is the longer part, it eould be divided into 3 then the width into 2

Length of the section = 1/3 ÷ 3

= 1/9 yd

Width of the section = 1/4 ÷ 2

= 1/8 yd

Area of the section = length of the section × width of the section

= 1/8 × 1/9

= 1/72 yd^2

my answer is$ 12

step-by-step explanation:

because 15 -2=12

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
