18=p+d+n, 3p=d, 2n=d
The lowest number that is divisible by 3&2 is 6 so, there is 6 nickels.
There is 6 nickels and there is half of that in dimes, 3 dimes.
There is three times the amount of pennies of dimes. 3*3=9. There is 9 pennies.
6 nickels + 3 dimes + 9 pennies= 18 coins

Which question is equivalent to 5+n
Dima020 [189]

Answer:

the answer would be n+5

Step-by-step explanation:

5n is the same as saying 5 multiplied by n

n +5 would equal the same number

for example if n=2 then 5+2=7

and if we used n+5 it would be 2+5=7

and if you plugin n=2 for all the equations the only correct one is N+5

Ok so i was walking with my computer and fell in a hole and i cant get out what do i do HELP ME
Alexus [3.1K]

First you go on the computer and you know how there's always a FBI agent watching you? You tell the FBI agent that your stuck in a hole and you need help. Then the FBI agent will send their team to come and get you but it won't be so easy because why? The little old lady you ran over decided to get revenge and set up a trap. so now it's the FBI vs The little old lady

the FBI starts to shoot at the Old Lady but she moves so fast she like lighting then she goes to attack the FBI agent but then the FBI agent reveals himself as the her grandson! Apparently he was able to get away and survive her attack since this caught the old lady off guard the grandson smashes cookies into her face and help you out of the hole

your welcome
