Answer: the service charge per hour for premium services is $5.5
the service charge per hour for regular services is $3
Step-by-step explanation:
Let x represent the service charge per hour for premium services.
Let y represent the service charge per hour for regular services.
One customer was charged $38 after spending 2 h in premium areas and 9 regular hours. It means that
2x + 9y = 38- - - - - - - - - - - 1
Another customer spent 3 h in premium areas and 6 regular hours and was charged $34.50. It means that
3x + 6y = 34.5- - - - - - - - - - -2
We would eliminate x by multiplying equation 1 by 3 and equation 2 by 2. It becomes
6x + 27y = 114
6x + 12y = 69
Subtracting, it becomes
15y = 45
y = 45/15
y = 3
Substituting y = 3 into equation 1, it becomes
2x + 9 × 3 = 38
2x + 27 = 38
2x = 38 - 27 = 11
x = 11/2 = 5.5

Answer:
All of the above.
Step-by-step explanation:
-185/100 is equal to -1.85.
-1.08 is greater because it is closer to 0 than -1.85.
190/100 is equal to 1.9. That's greater because it's in the positives.
-35/20 is equal to -1.75, which is closer to 0 than -1.85.
Therefore, all of the options are greater.
Answer:
14
Step-by-step explanation:
1) To find the distance between two points you'll need to use the distance formula:
d=
2) Figure out which points you'll want to set:
(x1,y1) = (-4,2) (x2,y2) = (10,2)
3) Substitute your values into the formula:
I think the answer is B because that is the only answer that could make sense.
