There are nine boxes in each pack. Garth bought 2 packs, all together containing 18 boxes. So 18÷2=9. Rico bought 4 packs, so 36 boxes divided by 4 equals 9. And so on. Your answer is 9 boxes = 1 pack.
Answer: 10 weeks
Step-by-step explanation:
Nilda's money = 250 +15x being x the number of weeks that have passed
Lona's money= 200+20x
If they have the same amount, then
250+15x=200+20x
250-200=(20-15)x
50=5x
50/5=x
10=x
You could use perturbation method to calculate this sum. Let's start from:
On the other hand, we have:
So from (1) and (2) we have:
Now, let's try to calculate sum
, but this time we use perturbation method.
but:
When we join both equation there will be:
So the answer is:
Sorry for my bad english, but i hope it won't be a big problem :)
If you have 3/5 marbles and you got 4/3more marbles then all you have to do is:3/5 x 3/3 and get 9/15.For 4/3 you multiply 4/3 x 5/5 and get 20/15.You simplify this and get 1 5/15.Now all you do is add them and get 1 14/15. Hope this helped you :-).
