Substitute in the points. It doesn't matter if they ar pe variables or not, since the variable b is used already in the equation, making it possible to find.
Substitute in the y value for the y in the equation and do the same for the x.
-3=2b+b
-3=3b
-1=b
b is -1.

The answer is C, between 40 and 60
We have been given that a friend has tickets to a concert and who selects 2 of them at random to give to you and we are also told that your friend has 13 tickets of which 5 are in the front row and 8 are in the tenth row.
We are asked to find out probability that both of the tickets you receive are in the front row.
In order to find out the probability that both of the tickets you receive are in the front row we will use probability formula.
Now let us find out total number of possible outcomes,
Now we can find out probability of getting both tickets in the front row by substituting our values in probability formula.
Answer: 6
Step-by-step explanation:
X = oranges / y = apples
x - 2 = 2y and 0.5x - 0.5y = 4
x - 2 = 2y
+2 +2
x = 2y + 2
0.5x - 0.5y = 4
2(0.5x - 0.5y = 4)
x - y = 8
Substitute
(x) - y = 8
(2y + 2) - y = 8
3y + 2 = 8
- 2 -2
3y = 6
y = 2
Substitute again
x = 2y + 2
x = 2(2) + 2
x = 4 + 2
x = 6
