can someone solve immediately
OpenStudy (anonymous):
use x as your main unknown variable
OpenStudy (anonymous):
let x be the number of nickels. Then there are x+2 dimes and x+4 quarters. You have $1.60 so we have the equation: .05x+.1(x+2)+.25(x+4)=1.6 .4x+1.2=1.6 .4x=.4 x=1 1 nickel, 3 dimes, 5 quarters.
