17 + (-5) is what I believe you are trying to ask. In that case it would be 12. Hope I helped! :)

topjm [15]

Answer:

211.7 Per Day 8.8 Per Hour

Step-by-step explanation:

First you do 1482/7 which gives you an average for each day (211.7)

Then you take 211.7  and divide that by 24 because there are 24 hours in a day and doing so would give you 8.8

Find the value of x to the nearest tenth.<br>​
Oksi-84 [34.3K]

Ok i hope this helps and if it does pls give me brainliest!

So the longest line is 8 and makes a 90 degree angle with another smaller line which is labled 3.6. X is longer than 3.6 ( only by a little bit) But it looks like its half of the longest line (8). So i think the answer would be X equals 4. But i was thinking about it more i relized that you would prob just divide 8 by 3.6 which would be 2.22222 .... And that rounded tot he nearest 10th would be 2.2.
