It’s -7/2
If it’s wrong I’ll correct it in the comments
All you do is 570 multiplied by 7 on a calculator and you get your answer which is 3,990
The mean of a set of numbers is the average. In this problem, add all of the numbers together ( negative numbers for the losses) and then divide by the amount of games total.
Here are the numbers we have to use:
+7
-3
-2
+4
+9
the problem would be 7-3-2+4+9=15
Now divide 15 by your total amount of games which would be 5.
15/5=3
The average difference would be 3. Now a rule in math is to answer a word problem with a sentence.
The mean difference in scores over the five games played would be 3.
Hope this helps!
Maybe it’s 2? Let me know if I’m wrong
Answer: <span>-2x-10=-2(x+5)</span>
<span>
-2x-10
Taking out common factor -2
= -2( x + 5 )</span>
