The right answer is the constant of proportionality
If two variables are related and this relationship is that there is a<em> constant ratio</em> between them, then we are talking about proportionality. There are two types of proportionality.
1) Direct Proportionality:
In a mathematical language this is given by this equation:
where 
is in fact this constant of proportionality. If 
<em>increases,</em> 
also <em>increases</em> at the same rate. On the other hand, If <em> decreases, </em> also <em>decreases</em> at the same rate.
2) Inverse Proportionality:
In a mathematical language this is given by this equation:
where is also called the constant of proportionality. If <em>increases,</em> <em>decreases</em> at the same rate. On the other hand, If <em>decreases,</em> <em>increases</em> at the same rate.
Answer:
-4(7 + 3a) - 6a(4a - 5) = <em><u>−24</u></em>
<em><u>+18a−28</u></em>
Step-by-step explanation:
2/3 times 90/1 equals 180/3, which is 60 degrees.
Im not sure but I think it’s Y/2-2 (the y and 2 is a fraction)
I believe it’s 0.9, or 9/10.
