What are the numbers that are supposed to be plugged in?
The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?
Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10
Answer:
the answer would be y= -40
x = -3, y = -2
Substitute the values of x and y to the equation xy = k:
k = (-3)(-2)
k = 6
If 2 1/2 centimeters make 1 inch, do 12 x 2 1/2, you should get 30 centimeters
