Five lemons costs 1.80.what is the cost per lemon. at this rate ,what is the cost of mine lemons

.36 per lemon

9 lemons is 3.24

Step-by-step explanation:

To find the cost per lemon, we take the total cost and divide by the number of lemons

1.80/ 5 =.36

It cost .36 per lemon

We want to buy 9 lemons

Multiply 9 by the cost per lemon

9 * .36 =3.24

The cost for 9 lemons is 3.24

{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

answer:   {x = -1/2 ,   y = -1
