Context ? i need more info.
9/10 is .9
51 subtracted by 6 is 45
45 multiplied by .9 is 50
.9 multiplied by 50 is 45
45 plus 6 is 51
So you missing number would be 50.
Hope this helps!
Solution :- Given differential equation

So the characteristic equation will be
![r^{2} -16=0 ⇒r^{2} =16 ⇒[tex]r_{1}=4 \\or \\ r_{2}=-4](https://tex.z-dn.net/?f=r%5E%7B2%7D%20-16%3D0%3C%2Fp%3E%20%3Cp%3E%E2%87%92r%5E%7B2%7D%20%3D16%3C%2Fp%3E%20%3Cp%3E%E2%87%92%5Btex%5Dr_%7B1%7D%3D4%20%20%20%5C%5Cor%20%5C%5C%20r_%7B2%7D%3D-4)
so, the required function will be

⇒
ia solution of the given differential equation
where

Answer:
$70
Step-by-step explanation:
75 copies=$10.50
$10.50÷75= 0.14 <em>(to get the price of 1</em> <em>copy)</em>
0.14×500=$70
2 I think
because 180 times 2 is 360. And then it would be a full angle.
