Can you comment the question I will be happy to help
Any multipule of 5 ends with either a 0 or a 5
so we see that ther are no 0's in the list so it must end with 5
so the other 2 digits can be any number
wait, less than 600
so the first digit can be 1 or 3
some possible numbers are
135
175
195
315
375
395
those are the possible numbers
Answer:
y=56
Step-by-step explanation:
Subtract 13 from both sides y/7=8
plug numbers in 56 divided by 7 equals 8
so therefore y=56
Answer:
210 ways
Step-by-step explanation:
Given
--- total
--- selection
Required
In how many ways can be selection be done
Since orders does matter, then it is permutation.
This is calculated as:
![^nP_r = \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5EnP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
So, we have:
![^7P_3 = \frac{7!}{(7-3)!}](https://tex.z-dn.net/?f=%5E7P_3%20%3D%20%5Cfrac%7B7%21%7D%7B%287-3%29%21%7D)
![^7P_3 = \frac{7!}{4!}](https://tex.z-dn.net/?f=%5E7P_3%20%3D%20%5Cfrac%7B7%21%7D%7B4%21%7D)
Solve each factorial
![^7P_3 = \frac{7*6*5*4!}{4!}](https://tex.z-dn.net/?f=%5E7P_3%20%3D%20%5Cfrac%7B7%2A6%2A5%2A4%21%7D%7B4%21%7D)
![^7P_3 = 7*6*5](https://tex.z-dn.net/?f=%5E7P_3%20%3D%207%2A6%2A5)
![^7P_3 = 210](https://tex.z-dn.net/?f=%5E7P_3%20%3D%20210)
