Answer:
76 birds
Step-by-step explanation:
Let x = the number of birds
Let y = the number of cats
x + y = 35 y = 35 - x
4.50x + 8.50y = 221.50 Multiply the whole equation by 100.
450x + 850y = 22150
450x + 850(35 - x) = 22150
450x + 29750 - 850x = 22150
-100x = -7600
x = 76 birds
10×4,000=40,000 because all u do is add an extra zero everything you multiple something by ten
