Answer:
72
Step-by-step explanation:
<em>Since the ratio of blue jays to robin's was 6 to 7 then if there were 84 robins how many blue jays were there.</em>
<em>6 to 7 can also be express as 6/7</em>
<em>Thus, we can set up a proportion</em>
<em>6/7 = x/84</em>
<em>Now, we have to solve for x</em>
<em>x = 72</em>
<em>Hence, if there were 84 robin there would be 72 blue jays.</em>

1. (0.5)2=1
2. (-0.2) + (-0.05) = -0.25
3. |-3 + 2.75| = 0.25
4. -(-0.25) = 0.25
5. 2x - 1.75x = 0.25x
So your answers are 3 and 4.
