8x-9y=11
First you move the 8x because you have to leave the 9y alone
8x-9y=11
-8x -8x
-9y=11-8x
Now you have to move the -9, so the inverse of multiplying is dividing so you divide -9.
-9y/-9= 11/-9 -8x/-9
since you can't have negative as a denominator it would be:
y= -11/9+8x/9

Step-by-step explanation:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.
7x5x25x11x10=96250

Answer:
Step-by-step explanation:
Breakeven is the revenue with no profit or loss. The money spent is same as money made.
<h3>Money spent is</h3>
<h3>Money made is</h3>
<h3>Since these are same, the number of pies is</h3>
- 200 + 0.25x = 1.5x
- 1.5x - 0.25x = 200
- 1.25x = 200
- x = 200/1.25
- x = 160
<h3>The revenue is</h3>
- 200 + 0.25*160 =
- 200 + 40 =
- 240
M + w = 253m + 4w = 90 Let's do substitution, first by solving the first equation for m. m = 25 - w Substitute! 3(25 - w) + 4w = 9075 - 3w + 4w = 90w = 15 m = 25 - 15 = 10 Hope this helps!
