Answer:Rounding a number is when you take a number and "bump it up" or "bump it down" to a nearby and "cleaner" number. A number can be rounded to any place value you want. If you type in a number you wish to round below, and select what place value you want to round it to, this selection will show you how to round it!
Step-by-step explanation:
Part A:
Let be the time (in hours) that has passed since Alan/Soren has started to head for their apartment.
Alan works 6 miles away from the apartment and moves at a rate of 7 miles per hour towards his apartment
The distance remaining to Alan's apartment after hours is:
Soren works 8 miles away and moves at a rate of 12 miles per hour. The distance remaining to Soren's apartment after hours is:
Set the equations equal to each other to find how long it takes for them to be at the same distance from their apartment:
Add both sides by 12t
Subtract both sides by 6
Divide both sides by 5
They will be at the same distance from their apartment after 0.4 hours, or 2/5 hours.
Part B:
Set d equal to 0 for each equation
Alan's equation:
Add both sides by 7t
Divide both sides by 7
Soren's equation:
Add both sides by 12t
Divide both sides by 12 and simplify
Since , it takes less time for Soren to get to his apartment, which means Soren gets back first.
The difference in the amount of time (how much less time it took) between Soren and Alan is:
It took Soren 4/21 hours less than Alan to get back to his apartment.

For this case we have that by definition, the area of a rectangle is given by:
Where:
a: It is the length of the rectangle
b: It is the width of the rectangle
We have as data:
So:
We look for two numbers that when multiplied get -24 and when added get -5.
These numbers are -8 and 3:
Thus, the solutions are:
We choose the positive value, so the length of the rectangle is A = 8
Answer:
8 centimeters
The vertical line is solid, so it must contain the solution so the inequality must contain equal to.
Because the shaded region is to the right of the line the solution has to be greater than.
The equation would be X ≥ -2
