Answer:
x = 18.5
Step-by-step explanation:
Given
+ = 10
Multiply through by 4 to clear the fractions
2x + 3 = 40 ( subtract 3 from both sides )
2x = 37 ( divide both sides by 2 )
x = = 18.5
B.
Step-by-step explanation:
Since the details are not available, we have provided an overview of William's total fixed and variable expenses for the first year of college.
<h3>What are college costs?</h3>
There are five categories of college costs.
These college costs include tuition, room and board, books and supplies, personal expenses, and transportation.
Some of the college costs like tuition and room and board may be relatively fixed.
This leaves expenses like books and suppliers, personal expenses, and transportation relatively variable.
Thus, William needs to control his variable college costs so that they do not exceed the student loan.

Answer:
It would take the newer pump 4.5 hours to drain the pool
Step-by-step explanation:
Let's investigate first what is the fraction of the job done in the unit of time (hour in this case) by each pump if the work individually:
older pump: if it takes it 9 hours to complete the job, it does of the job in one hour.
newer pump: we don't know how long it takes (this is our unknown) so we call it "x hours". Therefore, in the unit of time (in one hour) it would have completed of the total job.
both pumps together: since it takes both 3 hours to complete the job, in one hour they do of the job.
Now, we can write the following equation about fractions of the job done:
<em>The fraction of the job done by the older pump plus the fraction of the job done by the newer pump in one hour should total the fraction of the job done when they work together.</em> That is in mathematical terms:
and solving for x:
