Answer:
$420
Step-by-step explanation:
130x12=1560
165x12=1980
1980-1560=420
According to a daylight calculator for Fairbanks, AK, sun rises at 07:40 and sun sets at 20:12, giving 12 hours and 32 minutes of daylight.
Note that it is not a mistake that daylight is not exactly 12 hours on that day due to refraction of the sun's rays at sunrise and sunset.
At Fairbanks, near equality to 12 hours occurs on March 16 with sunrise at 07:58 and sunset at 19:57.
Coordinates of R (4,10)
•————•————•
(?,?) (5,9) (6,8)
You have to see how the x & y changed from point M to S and do the same thing for point R to M
M S
(5,9) >>>> (6,8) (x+1, y-1)
R M
(4, 10) >>>> (5,9) (x+1, y-1)
Answer: x=63, y=52, z=48
Step-by-step explanation:
The complete question in english is:
The sum of 3 natural numbers is 163. By subtracting the third number from the sum of the first two numbers, we get 67. By subtracting the first number from the sum of the last 2 numbers, we get 37. Determine the 3 numbers
According to this we have a system with three equations and three unknown values:
(1)
(2)
(3)
Let's begin by isolating 
from (1):
(4)
And substitute (4) in (2):
(5)
Isolating 
:
(6) We have found the first number
Substituting (6) in (1):
(7)
Adding (7) to (3):
We have the following:
Isolating 
:
(8) This is the second number
Substituting (6) and (8) in (1):
(9)
Isolating :
(10) This is the third number
Answer:
It would be y = 2x+4
Step-by-step explanation:
This is because Isabella has started with 4 baked pies and is gaining additional pies with in amounts of 2 pies.
With this, 4 would be by itself and 2 would be attached to the variable x for the unknown amount of additional pies.
Lastly, you would have this all equaling y, as y is the total amount of pies.
