Answer:
2x−5y=12
y = 2/5x + −12/5
Answer is x = 5/2y + 6 because....
First, Add 5y to both sides.
2x − 5y + 5y = 12 + 5y
Then, Divide both sides by 2.
Therefor, your answer is going to be x = 5/2y + 6

Answer:
47.5! Ask if you wanna know how exactly i got this and the formulas!
Step-by-step explanation:
3 x 5 = 15
<em>15 / 2 = 7.5</em>
<em>5 x 5 = 25</em>
14 - 8 = 6
6 x 5 = 30
<em>30/2 = 15</em>
<em></em>
<em>7.5 + 25 + 15 = 47.5</em>

370
20%= 0.2
0.2(360)=72
360+72=432
432-50=382
Answer:
<h2><u><em>8 feet</em></u></h2>
Step-by-step explanation:
<u><em>Given,</em></u>
Perimeter of a rectangular pool (P) = 40 feet
Length of the pool (l) = 12 feet
<u><em>Let,</em></u>
Width of the pool be = w
<u><em>As we know,</em></u>
- <em>Perimeter of a rectangle = 2(length + width)</em>
<u><em>Therefore,</em></u>
<em>By the problem,</em>
=> 2(l + w) = P
- <em>[On substituting the values of l = 12 and P = 40]</em>
=> 2(12 + w) = 40
- <em>[On multiplying 2 with 12 and w]</em>
=> 24 + 2w = 40
- <em>[On subtracting both sides with 24]</em>
=> 24 - 24 + 2w = 40 - 24
- <em>[On Simplifying]</em>
=> 2w = 16
- <em>[On Dividing both sides with 2]</em>
=> 
= 
- <em>[On Simplifying]</em>
=> w = 8
<u><em>Hence,</em></u>
<u><em>The required width of the pool is 8 feet. (Ans)</em></u>
