Part 2: Show your work to verify the solution for both equations.

Answer 2

I'm not sure on this one.

Answer 3

Me either, thanks though! ><

Answer 4

Np

Answer 5

I figured it out ! ^^

Answer 6

Great and thx for the medal!

Answer 7

So what was the answer

Answer 8

well you have to make two linear equations out of the information that you were given.
then with those equations you have to find a number that works with both equations.

11 + 1d & 9 + 2d
-----------------

11 + 1(1) = 12
9 + 2(1) = 11 , no

-----------------

11 + 1(2) = 13
9 + 2(2) = 13

-----------------

So if two drinks were ordered at the first restaurant;

11 + 1(2) = 13

If two drinks were ordered at the first restaurant;

9 + 2(2) = 13

So the solution is 2.

Answer 9

i guess in this case it would be two expressions xD

Answer 10

Yeah
