Answer:

x = 3

y = -1

( 3, -1 )

Step-by-step explanation:

5x + 2y = 13

 3x - y = 10

<em>Multiply "3x - y = 10 " by 2</em>

5x + 2y = 13

6x - 2y = 20

<em>Cancel out +2y and -2y</em>

11x = 33

<em>Divide both sides by 11</em>

x = 3

<h2><em><u>Substitute Into any equation:</u></em></h2>

 3(3) - y = 10

     9 - y = 10

         -y = 1

          y = -1

Answer:

Step-by-step explanation:

1km = 1000m

5a. 5.768km = 5768m = 57.7m

5b. 9.039km = 9039m = 90.4m

5c. 8.48km = 8480m = 84.8m

5d. 17.685km = 17685m = 17.7m

5e. 17.658km = 17658m = 17.7m

To round to the nearest 100m just divide by 100 and then round it off. like 57.68=57.7m because 8 is more than 5 so 6 becomes 7 to one decimal.

Rule is applied for all the other questions too.
