Answer:
28.75 or 28 3/4
Step-by-step explanation:
This equation is made for Long Division:
115/4
4 cannot go into 1 evenly.
4 can go into 11, 2 times.
4x2=8
11-8=3
4 can go into 35, 8 times.
35-32=3
Add a zero at the end, then divide 4 into 30.
4 goes into 30, 7 times.
30-28=2
Add another zero, then divide again.
4 goes into 20, 5 times.
20-20=0
So, after you hit an even number you can stop dividing and put in your answer.
28.75
Step-by-step explanation:
If two quantities x and y vary (change) together in such a manner that the ratio of their corresponding values remains constant, then x and y are said to be in direct proportion.
Answer:
y = -6/5x+56/5
Step-by-step explanation:
18x^2 + 2x + y^2 = 1
<span>==> 18(x^2 + x/9) + y^2 = 1 </span>
<span>==> 18(x^2 + x/9 + 1/324) + y^2 = 1 + 1/18 </span>
<span>==> 18(x + 1/18)^2 + y^2 = 19/18 </span>
<span>==> (x + 1/18)^2/19 + (y - 0)^2/(19/18) = 1. </span>
<span>By comparing this to the standard form of an ellipse, the center is at (-1/18, 0). </span>
