Estimate the answer by rounding each fraction to the nearest whole number and then adding.

20

Step-by-step explanation:

so you need to round to the nearest whole number. 9 2/9 is closer to 9 then to 10. 10 5/6 is closer to 11 then to 10. So, 9 plus 11, which is 20.

(hope this helps)

20 1/18

Step-by-step explanation:

9 2/9 + 10 5/6

83/9  + 65/6

361/18

20 1/18

Rounded to 20

darn 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
