Ok so to start, your unknown numbers will ne represented as x. The equation looks like this: x+x+1+x+2=228. You have your unknown number, the number plus one, and the numner plus two. To find the answer you divide 228 by 3. Those numbers are all equal though,so you play around with them until you get 75+75+1+75+2=228
Answer:
1*65
5*13
that is all answers one through twelve
Step-by-step explanation:
First of all, as I told you a little while ago, here is the formula
that solves ALL probability problems. Memorize this:
Probability =
(number of different successful possibilities)
divided by
(total number of all possibilities).
There are 10 keys in the bag. The total number of possible results
of pulling out one key out is 10.
3 of the keys start the car. The other 7 keys don't.
What are the 'successful' possibilities ?
The question asks for the probability of pulling keys that DON'T work.
So for this particular calculation, we're talking about choosing keys
that DON'T work. There are 7 of those.
The probability of drawing a key that doesn't work the first time is 7/10 .
Since the first key is put back in the bag and the bag is mixed, the
situation on the second draw is exactly the same as on the first one.
Thje probability of drawing a key that doesn't work the second time is 7/10 .
The probability of both events happening is (7/10)x(7/10) = 49/100 = 49% .
For this question, we want to find out what 9 / 12 equals as a percent
or x / 100. Therefore, we have a proportion here and can say:
9/12 = x/100
Now, at this point, we can cross multiply to get:
900 = 12x
Now, divide both sides by 12 to get x alone and find that:
x = 75 <==== FINAL ANSWER
so 9 is 12% of 75!
I hope that helps you out! Please let me know if you have any other questions!
Just keep going like i done in the picture replacing x and y so they add together to 6, you'll want to do negative numbers as well because the graph has a negative section
