<em>Hi!</em>
<em></em>
<em>These can be set up as systems of equations.</em>
<em> </em>
<em>Let b = the number of birds, and let d = the number of dogs.</em>
<em> </em>
<em>b + d = 21</em>
<em> </em>
<em>2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)</em>
<em> </em>
<em>You can solve this using either elimination or substitution.</em>
<em></em>
<em>Consider marking brainliest.</em>

around origin of 0,0
the image is flipped into the negative world if it is in posiitve or vice versa
6 foot =850
850÷6=141.667
then for 12 section
141.667x 12=1700 or
you find the ratio of 6:12
= 1:2
therefore 2×850=1700
