Answer:
7040
Step-by-step explanation:
C= 2000
B = 20/100 x 2000 = 400 + 2000 = 2400
A= 10/100 x 2400 = 240+2400= 2640
2000 + 2400 + 2640 = 7040
Answer:
The answer is D 6
Step-by-step explanation:
Multiply 3x2 and it equals 6
Answer:
d. 11.6
Step-by-step explanation:
The results of the first die and the second one are independent to each other. The expected value of Z is obtained, therefore, by summing the expected values of both X and Y, because Z = X+Y and X and Y are independent. As a result 
Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:

That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.
For example,

and

would work, but so would

and
I think that it your answer is 12.4 but im not 100% sure
