Pedro has 6.2 ounces of jelly. If he makes 4 sandwiches with an equal amount of jelly on each, how much jelly does he put on each one?

1.44 ounces

Step-by-step explanation:

6.2÷4=1.44

hope this helps

All you have to do is plug in the x and y values for each ordered pair into the left hand side of the equation and see if you get 15 = 15. If you do, the ordered pair is a solution; otherwise it is not a solution. For example, let's try (-2,-3); that is x = -2 and y = -3:

2x - 9y = 15
2(-2) - 9(-3) = 15
-4 - (-27) = 15
-4 + 27 = 15
23 = 15

This is obviously not true, so (-2,-3) is not a solution. Now you try it on each of the ordered pairs given in the problem statement.
