Algebra Practice Question
Algebra Questions, please help!?
I'm practical issues that I have a test tomorrow, and I could really need your help to make sure I did it correctly! Thanks! Please show all your work so that I can check against mine. The question is: a collector's item is $ 5 in dimes and nickels. It has three times more nickels to dimes. How and nickels many coins he did? Sample your work again, please! Thanks
$ 0.1 worth dimes, nickels and a value of $ 0.05. You have $ 5, and all that is composed of Dimes (D) and Nickels (N) so you can establish an equation … 5 = 0.1 D + 0.05 N also 3x dimes as many cents. So … 3D = N Here you have to use alternatives to give you an equation with one variable. Do you know 3D = N, so plug in 3D where you see "N" in the first equation. 5 = 0.05 + 0.1 D (3D) 5 = 0.1 D + 0.15 D 0.25 D = 5 (5/.25) = D = D 20. You have 20 dimes! 20 Reconnect to "D" in both equations and solve for how nickels. 3 (20) N = N = 60.
