Answer: x= (-3)
Step-by-step explanation:
3/4 [x-1] = [-3]
(x-1) = (-3) × 4/3
X-1 = -4
X= -3
Answer:
The value of x would be 16.
Step-by-step explanation:
In a data,
Median : middle value of the data when the data is written is ascending order.
While,
Here, the given data is,
4, 5, 6, 8, 10, and x
So, median = = = 7.
Number of the observations = 6,
Sum of the observations = 4+ 5+6+8+10+x = 33 + x
Thus,
Average = 
According to the question,
Therefore, the value of x would be 16.
Answer:
17
Step-by-step explanation:
Answer:
Apprentice = $800
Journeyman = $1600
carpenter = $4000
Step-by-step explanation:
Let the apprentice earns X dollars.
Then ,
Journeyman will make 200% of apprentice's earning which is 2X.
Also,
Carpenter makes 250% of the earning that journeyman makes.
Which is 2.5(2X) = 5X
Their total earning should come to $6400.
Thus,
X + 2X + 5X = 6400
8X = 6400.
X = $800
So,
Earning of apprentice = X = $800
Earning of Journeyman = 2X = $1600
Earning of carpenter = 5X = $4000
This is because when we do verification of an
identity, we must work separately on both sides, and to see in the end
if we can get an equality. Because if we square both sides, that already means
that we assume that the equality exist in the beginning, so no need to
verify the identity.
