A sixth number will be added to the list. What must it be in order for the mean to be 12?
Vlad1618 [11]

Answer:

16

Step-by-step explanation:

7+16+11+12+10= 56

12*6= 72

72-56= 16

Double check your work:

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

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
