Answer:
3.6
Step-by-step explanation:
The average of 9 scores is x.
average = (sum of scores)/(number of scores)
x = (sum of scores)/9
sum of scores = 9x
The sum of the 9 scores is 9x.
The tenth score is 36 more than x, so it is x + 36.
The sum of the 10 scores is 9x + x + 36 = 10x + 36.
The average of the 10 scores is (10x + 36)/10 = x + 3.6
The difference of averages is
x + 3.6 - x = 3.6
60/5 x 132/x
60x = 660
Divide 60 from both sides
x = 11 miles

Answer: Hi!
Since 5 is being multiplied by x, and x is equal to 2, be would multiply 5 and 2. 5 * 2 is equal to 10.

If he catches 2 out of 5, that mean he catches 14 out of x. We multiply 2 by 7 to get 14, so we multiply 7 by 5 to get 35. 35 balls were thrown at him. To check your work you can simply simplify 14/35 to get 2 out of 5 again. Hope this helps!
