Answer: x = 101.75
Step-by-step explanation:
Hi, to answer this question we have to solve the equation give, by isolating x:
8x-4 = 810
The first step is to Add 4 on both sides:
8x-4+4 = 810+4
8x = 814
Then we have to divide both sides by 8:
8x/8 = 814/8
Finally, the solution is:
x = 101.75

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>
