Given the equation :

We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :

<h2><em>Okay so these are the answers from top to bottom.</em></h2><h2><em>x = 2 and y = x + 8 so 2 + 8 = 10.</em></h2><h2><em>x = 0 and y = x + 8 so 0 + 8 = 8.</em></h2><h2><em>x = 4 and y = x + 8 so 4 + 8 = 12.</em></h2><h2><em>10</em></h2><h2><em>8</em></h2><h2><em>12</em></h2><h2><em>Hope this helps and have a great day...!</em></h2>
I believe the answer is x = 1
