<h2>
Step-by-step explanation:</h2>
We will use the Gaussian elimination method to solve this problem. To do so, let's follow the following steps:
Step 1: Let's multiply first equation by −2. Next, add the result to the second equation. So:
Step 2: Let's multiply first equation by −1. Next, add the result to the third equation. Thus:
Step 3: Let's multiply second equation by −35, Next, add the result to the third equation. Therefore:
Step 4: solve for z, then for y, then for x:
By substituting 
into the first equation, we get the 
. So:
It is 8300 cause 5 is bigger than 2 so 83 and hen 00 : 83000
The median tell you how many you have in common.
So hmm notice the picture below
thus, the perimeter of the gutter is just w + w + l, or 2w +l
thus
take the derivative of A(w), zero it out, check any critical points in the interval of (0, 22), for a maxima
recall, the aluminum sheet is just 22inches long, thus, whatever the "depth" or "w" is, has to be more than 0, and less than 22
To solve this question you will need to subtract -3.8 by 5.6 which is equal to -9.4. So the final answer is -9.4°C
