Are you working with simple interest?
A m8 the rule is to divide by 2
8x-27=3x+58, get all x values on one side and constants on the other 5x=85, now divide both sides by 5. We get the answer of x=17
The method that can be used to randomly choose these 500 people is the use of systematic random sampling.
<h3>What is random sampling?</h3>
Random sampling is defined as the method of sampling in which the whole sampling frame is being considered.
In order the survey a community of people to see whether they are willing to have their taxes increased for one year to fund the construction of the skate park, both the male and female should be considered.
The systematic random sampling will give the both male and female equal opportunity to the chosen.

Answer:
(4,-1)
Step-by-step explanation:
Given
3 Co-ordinates of a parallelogram ABCD
A=(1,-3)
B=(1,0)
C=(4,2)
D=(a,b)
One of the property of a parallelogram is that the diagonals bisect each other
In this case, AC and BD bisect each other, Therefore the middle point of AC and BD coincide
⇒Mid-point of AC= Mid-point of BD
(mid point of 2 points (x,y) and (k,l) is )
Compare x and y co-ordinates on both sides
⇒
a=4
⇒
b=-1
Therefore D=(4,-1)
