Lia has a red ribbon that is 2 1/12 inches long she has a blue ribbon that is 4 time as many inches as long how many inches long is the blue ribbon in fraction

8 1/3 inches

Step-by-step explanation:

Length of the ribbon = 2 1/12 inches

Blue ribbon is 4 time as many inches as long as red

Length of the blue ribbon = 4 * 2 1/12

Length of the blue ribbon = 4 * 25/12

Length of the blue ribbon = 100/12

Length of the blue ribbon= 25/3

Length of the blue ribbon = 8 1/3 inches

Hence the blue ribbon is 8 1/3 inches long

{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
