For what value of x will 55 and x have the mean (average) as 67
2 answers:
<span>To calculate the mean of two numbers you add them together and divide the sum by 2.
We can set up an equation for this problem: (x+55)/2 = 67
Now we need so solve for x: (x+55) = 67x2
x+55 = 134
x = 134-55
x = 79
Hope this helps, and May the Force Be With You!

If (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
