The average of two numbers is 41. If one of the numbers is 27, what is the other number?
nydimaria [60]

The other number if the average of two numbers is 41 and one is 27 is 55

<h3>How to calculate the average of numbers?</h3>

Average of number is also known as the mean.

Let the unknown number be "x" such that:

x +27/2 = 41

Determine the value of x

x + 27 = 2(41)
x + 27 = 82
x = 82 - 27

x = 55

Hence the other number if the average of two numbers is 41 and one is 27 is 55

(3/5)·x = - 48;

x = (5/3)·(-48);

x = 5·(-16);

x = - 80;
