Answer:
Points A, C, and D are coplanar, and Point B is noncollinear.
Step-by-step explanation:
We know that there are 21 buttons total. x is the number of small buttons and y is the number of large buttons.
Therefore, our first equation should be x+y = 21.
We know the small buttons sell for 3 dollars, meaning 3x represents how much is made from the small buttons. The larger buttons sell for 4 dollars, meaning 4y is how much is made from the large buttons.
We also know that the total of the buttons sold is 68 dollars. Therefore 3x + 4y = 68 is our second equation.
From this information, the answer is the first set.
2/9 + 4/9
first add them and then divide to get the simplest form ....
=6/9
=2/3 ...
Hope it helps !!!
