Answer:
C = 12 + 15(x - 4)
C = 15x - 48
Step-by-step explanation:
Let the number of hours = t
The total amount Miguel earns =
C
To edit a manuscript, Miguel charges 12 dollars per hour for the first 4 hours and 15 dollars per hour after the first 4 hours.
C = 12 + 15(x - 4)
Expand the t
C = 12 + 15x - 60
C = 15x - 48
Therefore, an expression for the amount, in dollars, Miguel charges if it takes him t hours to edit a manuscript, where t>4 is given as:
C = 15x - 48

When you do 27 times x squared times z all over -3, then times that by x squared times z to the sixth power, you get -9x^4z^7
Answer:
if it's less than 7.66km use Royal, if more than 7.66 use Queen's
Step-by-step explanation:
To get the answer you can set up mutliple equations
For Queen's Cab Company
2.70 + 0.20x = ?
for Royal Cab Company
1.55 + 0.35x = ?
Since you didn't give a distance which is what will determine which is cheaper we can solve as a set of equations.
2.70 + 0.20x = 1.55 + 0.35x
1.15 = .15x
x = 7.66
So this lets you know that at 7.66 km Royal cab company becomes more expensive due to their pence per km.
So if it's less than 7.66km use Royal, if more use Queen's
Answer:
B
Step-by-step explanation:
A: No, because you can't switch signs of a number to another sign unless you change the number itself.
B: Yes. It has the same numbers and signs and the result is negative (there are an odd amount of negative signs)
Least to Greatest
1/8 1/3 1/2
Hope this helps!!
