Associative means that you can move the parenthesis around the problem and still get the same answer. like (4+2)+3=4+(2+3)
first & sixth are the true
False true true false true false
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>

Find the Greatest Common Factor (GCF)
GCF = 5
Factor out the GCF (Write the GCF first, and then in parenthesis, divide each term by the GCF.)
5(5x/5 + 15/5)
Simplify each term in parenthesis
<u>5(x + 3) </u>
