Question 171291: Mr.Samuels has 150 pennies in two jars. There are 40 more pennies in one jar than in the other. How many pennies are in each jar?
I think it might be 150 div by 2 equals 75, then take 75 plus 40 equals 115, so one jar would have 35 pennies and the other jar would have 115, because you would take 75 plus 40 equals 115 and then add the 35 from the other jar and get 150 pennies total. Is this correct?

Question 174718: I have 30 coins, all nickels, dimes, and quarters, worth $4.60. There are two more dimes than quarters. How many of each kind of coin do I have?
For this problem, it was required to use three equations:
i tried the following:
n+d+q=30
5n+10d+25q=460
d=2+q
n+d+q=30
5n+10d+25q=460
-5(n+d+q=30)
5n+10d+25q=460
-10n-10d-10q=-300
5n+10d+25q=460
-5n+15q=160; equation A
5n+10d+25q=460
d=2+q
5n+20+10q+25q=460
5n+20+35q=460
5n+35q=440; equation B
-5n+15q=160
5n+35q=440
50q= 600
q=12
-5n+15(12)=160
-5n+180=160
-5n=-20
n=4
(4)+d+(12)=30
16+d=30
d=14
5(4)+10(14)+25(12)=460
20+140+300=460
20+440=460
460=460
Would this be the correct answer??

I have tried a few equations:
1) 5(x-5)+10(4x)+25(x+15)=205
2) 5(x-20)+10(4x-15)+25x=205
3) 5x+10(4x)+25x+=205
I know this can be solved with multiple variables, but I am suppose to solve it with one. Please help.

Question 178282: I have a word problem that I have worked two diffrent ways and I am still not able to come up with the answer.
THe problem is:
A store employee is counting $10.00 and $20.00 bills. If there are 6 times as many $10 bills as $20 bills and the total amount is $1760, find the number of each type of bill.
10x+60+20x=1760
30x+60=1760---then subtract 60 from both sides I get
30x=1700
x=56.6666666
I am not sure what I am doing wrong so any help with this would be greatly appreciated!!
Thanks in Advance.
