Answer:
0.0143 in decimal form
Step-by-step explanation:
35 + 3 = 83x
35x + 3 = 83
35 + 3x = 83
The value of x from the given equation is -8. Luca did mistake while multiplying 5 inside the terms of a bracket.
The given equation is 2-6x=5-5(x-1).
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved as follows:
Using distributive property multiply 5 to the terms in a bracket.
That is, 2-6x=5-5x+5
⇒ 2-6x=10-5x
Add 5x to both the sides of an equation
That is, 2-6x+5x=10-5x+5x
⇒ 2-x = 10
Subtract 2 to both the sides of an equation
That is, -x=8
Multiply -1 to to both the sides of an equation
So, x=-8
The value of x from the given equation is -8. Luca did mistake while multiplying 5 inside the terms of a bracket.

The missing dataset is 81 at the 4th position.
We have the following data set -
82, 87, 77, 70, 80, 88
whose Median is - 81
We have to find out the missing data in this dataset.
If a set consist of odd number of elements, then the median of that set of numbers is the is the element at the position .
Let the missing element be x. Now, the data set becomes -
82, 87, 77, 70, 80, 88, x
To total number of elements in the dataset = 7, which is a odd number.
The element at the position for odd number of elements equals to Median which is equal to 81.
Hence, the missing dataset is 81 at the position - = 4th position.
