Answer:
9 parts of beans and 12 parts of ground beef is in the chilli.
Step-by-step explanation:
Given:
In a pot of chilli, there are 3 parts of beans to every 4 parts of ground beef.
If a total of 21 combined parts we're used to make.
Now, to find each ingredients is in the chilli.
As, given there are 3 parts of beans to every 4 parts of ground beef.
Let the beans be [tex]3x.[/tex]
And the ground beef be [tex]4x.[/tex]
Total combined parts = 21.
Now, to get the each ingredients we solve an equation:
[tex]3x+4x=21[/tex]
[tex]7x=21[/tex]
Dividing both sides by 7 we get:
[tex]x=3.[/tex]
The beans = [tex]3x=3\times 3=9.[/tex]
The ground beef = [tex]4x=4\times 3=12[/tex].
Therefore, 9 parts of beans and 12 parts of ground beef is in the chilli.
