Answer:
22
Step-by-step explanation:
We can write an equation:
(7+13+10+x)/4=13
x represents the number that needs to be added to get an average of
(7+13+10+x)/4=13
(30+x)/4=13
30+x=52
x=22
The number is 22
Hope this helps! Have a wonderful day :)
The answer for the first one (-2,6) is to go left two and up six. on the x line (horizontal) left is negative and right is positive. on the y line (vertical) down is negative and up is positive. 0 is where the two lines meet.
hope this helps!
X+6 maybe

If the number was 2.15, you would round to 2.2 because any place that is 5 or greater rounds up and any place less than 5 rounds down.
.1 is the tenths place
.11 is the one hundredths places
