Question

PLEASE HELP !?!?!!?!?!

The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.


Dogs
Birds
40
10
50
8
b = 4d; b = 40

b = 4d; b = 2.5

b = 400 over d; b= 4000

b = 400 over d b = 40

Answer 1

try to eyeball it !

see if you get the ratio of \(\Large dogs/birds \) same for both set of values

or you get \(\Large dogs \times birds \) same for both set of values.

Answer 2

is it a?

Answer 3

lets check!

b= 4d
b= 8, d= 50

is 8 = 4*50 ?
nopes, thats not true

so its not A

Answer 4

so its either c or d ?

Answer 5

for 10 dogs, d =10

just plug this in b = 400/d

b= 400/10 = ...

Answer 6

b=40

Answer 7

\(\huge \checkmark \)
