H=10+(10 1/3) is a correct equation. The answer should be h=13.33
You can do this one simply just by plugging in the values of x and y for each answer.
Note: (0,5) is just a way to right x=0 and y=5
Try answer A (0,5)




This is not true. 5 is not bigger than 5 so A is not the answer
Try answer B (1,7)




This is true so answer B works!
Might as well try answer C (7,1)




1 is obviously not greater than 12 so C does not work
The answer is B (1,7)
The first one is D. (2+11)7=7(2+11)
I'm not sure of the second one, I apologize.
To disembark means to leave / get off something (typically used when talking about vehicles)
e.g.:
The passengers disembarked the ship at 6:00.
Let's assume two variables x and y which represent the local and international calls respectively.
x + y = 852 = total number of minutes which were consumed by the company (equation 1)
0.06*x+ 0.15 y =69.84 = total price which was charged for the phone calls (Equation 2)
from equation 1:-
x=852 -y (sub in equation 2)
0.06 (852 - y) + 0.15 y =69.84
51.12 -0.06 y +0.15 y =69.84 (subtracting both sides by 51.12)
0.09 y =18.74
y= 208 minutes = international minutes (sub in 1)
208+x=852 (By subtracting both sides by 208)
x = 852-208 = 644 minutes = local minutes
