x = -10/3 - 2y/3
Answer: A. 40%
Step-by-step explanation:
to find the percentage decrease, first you have to subtract $6,300 from $10,500, which equals $4,200. This is the amount decreased from the price of the car. Then, to find the percentage that $4,200 is to $10,500, you have to divide 4,200 by 10,500. This should give you 0.4, the percentage is this number multiplied by 100. This should give you the number 40, which means that the percentage decrease of the price of the car; 40%.

Step-by-step explanation:
a) The social network contains four people networking with six other people, altogether there are ten people netwoking together.
So, if one person in one social network, network with five others in the network, but when it is paired, we have eight altogether in the first case.
When the other case are paired, it is discovered that, the remaining pair is left with two people networking with three other people.
b) Altogether, when it is paired in each case, the following summation provides the number of people that network with each other:
First case = 1 + 5 + 2 = 8
Second case = 5 + 4 + 3 = 12
Altogether it is 20 people
