Answer:
5x
Step-by-step explanation:
If the blank were to be occupied with 5x there would be no solutions
Observe...
5x - 8 = 5x + 2
* subtract 5x from each side *
5x - 5x cancels out
5x - 5x cancels out
we're left with -8 = 2
which is not true
Hence if the blank = 5x the equation will have no solution

Hope this helps!
Let’s make an equation 5x=15.25. We should get x by itself by dividing both sides by 5. Which should leave x=3.5, which would mean he’d have to run faster, so no. It’s not reasonable
Hello! I can help!
10:
a. 4-5 magazines interval contains the fewest data values.
b. There are 20 students in the class. 15 + 3 + 2 is 20.
c. Ignore the 6-7 interval and count the students from the others. 17/20 students read less than 6 magazines. 85% of students read less than 6 magazines.
d. You can’t exactly find the mean of the data, because you don’t know the exact number of how many each student read. The median would be in the range of 2-3, but you can’t find that either. You can’t find any of them without the exact numbers.
11. There were way more than 12% of songs that took 5-8 seconds to download. The error was getting the number of songs that took that long to download and putting it as a percentage. 12/36 songs took 5-8 seconds to download. 12/36 equals 1/3 (0.333) or simply 33%. The real answer is that 33% of the songs took 5-8 seconds to download.
