We will represent everything in cents
nickles are worth 5 cents and dimes are 10 cents
n=number of nickles
d=number of dimes
60 total coins
n+d=60
total is 430 cents
5n+10d=430
divide both sides by 5
n+2d=86
we gots
n+d=60 and
n+2d=86
eliminate
multiply first equation by -1 and add to 2nd equation
-n-d=-60
<u>n+2d=86 +</u>
0n+1d=26
d=26
so
n+d=60
n+26=60
n=34
34 nickles and 26 dimes
I Think the answer is 31 because 20-5 is 15 so 36-5 is 31

The dekameter (or decameter) first needs to be a translated into how many
the meters. deka means 10, so a dekameter it must be 10 meters. So we have to
divide 250 by 10, and then we will come up with 25 dekameters.
hope that helps!!
Answer:
The answer is A.
Step-by-step explanation:
