Answer:
The temperature on the 5th day was of -9ºC.
Step-by-step explanation:
Mean of a data-set
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
The mean temperature for the first 4 days in January was 1°C.
This means that during the first 4 days, the sum of the temperatures was 4*1 = 4ºC.
The mean temperature for the first 5 days in January was -1°C.
First 4 days: Sum of 4º
5th day: Temperature of x.
The mean is -1, so:
The temperature on the 5th day was of -9ºC.
Answer:
LM > MK > KL
Step-by-step explanation:
Given: ΔKLM , m∠K = 101° , m∠L = 67°
By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°
By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.
Note the angles:
m∠M = 12° ∴ Side LK = shortest
m∠K = 101° ∴ Side ML = longest
m∠L = 67° ∴ Side KM = in between
∴ LK < KM < ML
A) LM > MK > KL is your answer.

Simplify, you get 12n+4=-6n-14. You simplify even more to get n=-1.
3 is the greatest common factor, because both numbers are divisible only by 3.
