The doble number line shows that jonah needs 28 seconds to fold 2 shirts. based on the double number line, how long does jonah need to fold 5 shirts?

We are given the double number line shows that Jonah needs 28 seconds to fold 2 shirts.

Let us find the number of seconds to fold 1 shirt.

In order to find the number of seconds to fold 1 shirt, we need to divide 28 by 2.

On dividing 28 by 2, we get

28/2 = 14 seconds.

We need to find the number of seconds to fold 5 shirt.

Each 2 shirts needs 28 seconds.

Therefore, 4 shirts would need = 28 + 28 = 56 seconds.

And 5 shirts would need = 28 + 28 + 14 = 56 + 14 = 70 seconds.

-2 is the right

{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
