Best ResponseYou've already chosen the best response.0Suppose you have four numbers (call them a,b,c,d). They have the following characteristics: a is a perfect cube b is a perfect square c is divisible by 10 d is ONLY divisible by 5 They are also related in the following ways: \[ca=4+b\] \[d/c = (a(d51)/a(c69))\] \[bcad = 2165\] \[5(d3a) = 80\] What is a, b, c, and d?

Best ResponseYou've already chosen the best response.0Oh, and just so it doesn't cause any confusion, the second equation can also be written as: \[d/c = (a(d51)\div(a(c69))\]

Best ResponseYou've already chosen the best response.1oh wait never mind what i said about d. from ca=4+b, i got c=4+b+a and i cross multiplied the second equation. and substituted c for 4+b+a that's what i have until now
