Answer:
-1/13
Step-by-step explanation:
5-x= 12x + 4
5-4=12x + x
1 = 13x
-1/13 = x
Answer:
Step-by-step explanation:
During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.
On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.
1 metric ton = 1,000 kilograms
To convert from kilograms to metric tons, divide by 1,000.
10,600÷1,000=10.6 metric tons
If you add them straight down:
2d-e = 7
d + e = 5
Then the e's cancel out.
You are left with 3d = 12
Then solve for d by dividing each side by 3.
Now you have d =4.
To solve for e go back into one of your original equations and substitute 4 for the d.
You can use either equation, so I'll choose the second one.
4 + e = 5
Now solve for e by subtracting each side by 4.
Now you have e = 1.
So your solutions are d = 4 and e = 1
