Same problem

-53
It is -2 for anyone who wants the answer
Can you tell me why?
2 equations:
(1) n+d=53
(2) 0.05n+0.1d = 4
(2) * 100 = 5n+10d = 400
(1) * 10 = 10n + 10d = 530
(1)-(2) = 5n=130 n=26
26 Nickels
i would think so.
3) https://web2.0calc.com/questions/help_44437
2) 2x^2-20=-50
2x^2+30
x=5
1) Foil and get 2+2sqrt(5) so 2+2=4
