Mean is a problem of addition and division.
What is a mean?
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
We can consider the following set of numbers.
= 1, 2, 3, 4, 5
The mean of 1, 2, 3, 4, 5.
= (1 + 2 + 3 + 4 + 5) / 5
= 15/5
= 3
We see that,
While calculating the mean we add all the given values and divide by the number of values added.
Thus,
Mean is a problem of addition and division.

The numbers such that when multiplied gives -140 and added gives -31
are, 4 and -35.
Here we have to find the numbers,
Which is when multiplied gives = - 140
And when they added give -31
Since we know that,
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Therefore,
Now to finding such number proceed :
1 and -140 is wrong because 1 + -140 = -139
-1 and 140 is wrong because -1 + 140 = 139
2 and -70 is wrong because 2 + -70 = -68
-2 and 70 is wrong because -2 + 70 = 68
4 and -35 is right because 4 + -35 = -31
Hence we can see that,
Such numbers are 4 and -35.

were trombones?
Answers
Answer: 76 trombones
Step-by-step explanation: The first thing to recognize is that 76% is out of 100%. So, in other terms, you can say that 76/100 is equal to the percentage given to us. If we know that, we can set up a ratio problem.
Here, you can cross multiply. (76x100) = (100xX) To make things simple, divide both sides by 100. In the end, you will get X = 76 trombones.
