Answer:
3_-1_-5
Step-by-step explanation:
-4(0)+3=3
-4(1)+3=-1
-4(2)+3=-5
N is the amount of sides
sum=13 times 180 =2340
N + d = 20....n = 20 - d
0.05n + 0.10d = 1.35
0.05(20 - d) + 0.10n = 1.35
1 - 0.05d + 0.10d = 1.35
-0.05d + 0.10d = 1.35 - 1
0.05d = 0.35
d = 0.35/0.05
d = 7 <==== 7 dimes
n + d = 20
n + 7 = 20
n = 20 - 7
n = 13 <=== 13 nickels
