Answer:x=20 y=70
Step-by-step explanation:
45 Cards
12 friends invited; 1/2 came 12 x 1/2=6
Let x stand for the number of cards each friend received
Armando kept 3
6x = 45-3
6x = 42
__ __
6 6
x = 7
Each friend received 7 cards
Volume=length*width*height (for a rectangular prism)
Plug in the values.
4 1/4*3*1 1/4= the volume
4 1/4*3= 12 3/4, so:
12 3/4 * 1 1/4 is correct as well.
The answer you checked is the correct answer.
I hope this helps!
