-2(A-b=6)
-2A+2b= -12
A-2b=2
-2A+2b = -12
-------------------
-A = -10
-A/-1 = -10/-1
A = 10
a-b=6
10 - b = 6
10-10-b = 6 -10
-b = -4
-b/-1 = 14/-1
b= 4
Check
a - 2b =2
10 - 2(4) =2
10 - 8 = 2
2=2

Answer:
The fact that the number of crimes and the population of students is positively correlated, means that as the total number of students increases, so does the total number of crimes.
The conclusion that closing schools will decrease crime is absurd. First of all, the variables might be totally unrelated, e.g. places with large number of students are places that have high populations. Higher crime rate are generally linked to neighborhoods or cities with high populations.
The idea of closing schools to fight crime is foolish because it will result in the opposite. Generally, students who go to school tend to be less engaged in criminal activities. The real problem here is that you should try to increase the number of students that attend schools in Glendale, not vice versa.

Step-by-step explanation:
Let C be the cost for 150 minutes of play time.
We have been given that Quinn is playing video games at a virtual reality game room. The game room charges 20 dollars for every 30 minutes of play time.
We will use proportions to find the cost for 150 minutes of play time as proportions states that two fractions are similar.
Upon substituting the given value we will get,
Upon cross multiplying our equation we will get,
Upon dividing both sides of equation by 30 we will get,
Therefore, Quinn need $100 to pay for 150 minutes of play time.
