Peter's salary is twice Anne's salary and half of David's salary. Then the average salary of Anne and David is _ of Peter's sala

satela [25.4K]

<h3><u>Answer:</u></h3>

Average of salary of Anne and David is 1.25 of Peter's Salary

<h3><u>Explanation:</u></h3>

In the question, relations between salaries of Peter, Anne, and David is given. From the given relations, we need to make few equations and calculate the average of Anne and David in terms of Peter's Salary.

Let us assume Peter's Salary as P.

Then we can calculate Anne's salary A = $\frac{P}{2}$ .

Also David's salary = D = $2 \times P$

Average of Anne's and David's salary = $\frac{A+D}{2}$

Average of Anne's and David's salary = $\frac{\frac{P}{2} + 2 \times P}{2}$

Average of Anne's and David's salary = $\frac{5 \times P}{4}$

Average = 1.25 \times P

Suppose the coordinate of p=2 and PQ=8. Where are the possible midpoints for PQ?

almond37 [142]

The possible midpoints for PQ are
c. -2 and 6

explanation:
coordinate of midpoint is 0.5(P+Q)=0.5(2+x)=1+0.5x
PQ=8 so |x-2|=8
x-2=8 or x-2=-8
so x<span>=10 or x=-6
coordinate of midpoint= 1+0.5x
x=10 we get 6 and x=-6 we get -2</span>
