A sixth number will be added to the list. What must it be in order for the mean to be 12?

Vlad1618 [11]

Answer:

Step-by-step explanation:

7+16+11+12+10= 56

In order to find the 6th number, you must multiply 12 and 6.

12*6= 72

72-56= 16

Double check your work:

7+16+11+12+10+16= 72

72/6= 12

If DF = 35 and EF = 12, what is DE?<br><br> ANSWER QUICK

Sholpan [36]

Straight lines can be divided into different segments

The value of DE is 23 units

We have:

$DF = 35$

$EF = 12$

Segment DF and EF have the same endpoint.

This means that, point E is located on segment DF

So, we have:

$DF = DE + EF$

Substitute known values

$35 = DE + 12$

Collect like terms

$DE = 35- 12$

$DE =23$

Hence, the value of DE is 23 units
