You are adding consecutive odd numbers to the number before. Starting with 1, add 3 to get 4. Add 5 to 4 to get 9. Add 7 to 9 to get 16, add 9 to 16 to get 25, add 11 to 25 to get 36. Trying to figure out how to write that as a recursive rule...
2 because rise/run so 8/4 which=2
Remove all the brackets
3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9 Collect like terms.
24 + 6x = 6 - 6x Add 6x to both sides.
24 + 6x + 6x = 6 Subtract 24 from both sides
12x = 6 - 24
12x = - 18 Divide by 12
x = - 18 /12
x = - 1.5
Check
3(7 + 2*(-1.5)) + 3 = ? 3(5 + -(1.5) - 9(-1.5 + 1)
3(7 - 3) + 3 =? 3(3.5) - 9*(-1/2)
3*4 + 3 =? 10.5 + 4.5
12 + 3 =? 15 And it checks.
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!
