Any ideas?

skullpatrol · Answer

Recall the definition of the average of a set of numbers is the sum of the numbers divided by the number of numbers.

whystudyalone3 · Answer

What kind of equation would I use to solve this?

skullpatrol · Answer

$$\huge 29 = \dfrac{25+26+29+32+x}{5}$$

mathmale · Answer

"average" is the key word here.  How does one go about finding the average of a group of numbers?  skullpatrol's response is excellent.

whystudyalone3 · Answer

29= 112 + x / 5

Is that right so far?

skullpatrol · Answer

You should multiply both sides by 5 first.

whystudyalone3 · Answer

do I multiply each of the numbers individually? Such as 25 * 5, 26 * 5, 29 * 5, 32 * 5?

mathmale · Answer

Multiply both sides by 5.  This will remove the fraction on the right side.  No, do not multiply each of those 4 given numbers individually.  Please type your result here, so that we can give you further feedback on what to do.
