Answer:
There are 91 dimes in the jar.
Step-by-step explanation:
5n+10d= 1455
n+d = 200
n=200-d
5(200-d) + 10d=1455
1000-5d+10d=1455
1000+5d=1455
5d=455
d=91
91 dimes
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
