(m + 12) / 9m = 5 / 9
cross multiply
(5)(9m) = 9(m + 12)
45m = 9m + 108
45m - 9m = 108
36m = 108
m = 108/36
m = 3 <==
Answer:
175 ways
Step-by-step explanation:
5 balls are red, and 7 balls are blue making a total of 12 balls.
4 balls are drawn from the box,
1 ball is red and 3 balls are blue out of the 4 drawn from the box.
We have to choose 1 ball from 5 red balls and 3 blue balls from 7 blue balls.
Since the order is not essential we use combinations to find out
5C1 * 7C3= 5*35 = 175 ways
Zeros do not count as a sigfig so when you do something like this problem just include the numbers until you hit your significant figure limit and then substitute zeros where you can. 20000
First find out what 10 percent of 50 is
Do 50/10
I got 5
Then do 5 times 9 to get your answer
You should get 45. Thanks (:
