First multiply both sides by 7
Your equation now looks like this:
x-28=0
Now move the constant to the other side causing it to change signs
The negative now becomes a positive
x=28
Now you are left with your answer:
x=28
Hope this helps! :3

Given: On each of 3 days the distance traveled by Derrick to school = 6.45 km
The distance rode by Derrick to library = 150 meters
Since, 1 m=
Thus, the distance rode by Derrick to library = 
The distance rode by Derrick to home = 500 meters.
Thus, the distance rode by Derrick to home = 
Distance he rode in each day = 
Now, Distance he rode in 3 days = 
About 95% of rats weight is between 2.5+2 *standard deviation=2.5+2*0.5=2.5+1=3.5 and 2.5-1=1.5 (1.5,3.5).
About 68% of rats weight is between (2.5-1*standard deviation, 2.5+1*standard deviation), (2,3).
This means that about 68 percent of rats in the city weigh between 2 pounds and 3 pounds. (solution b)
