PLEASE HELP FOR MEDAL!!! JUST SOME ALGEBRA HOMEWORK!!


Which equation can be used to solve the following word problem?


Emilio has 6 more nickels than dimes, and the total value of his coins is $2.10. How many nickels does he have? Let n represent the number of nickels.

0.10n + 0.05n + 6 = 2.10
0.10(n + 6) + 0.05n = 2.10
0.10(n - 6) + 0.05n = 2.10
0.10n + 0.05(n + 6) = 2.10

Answer 1

Wait... What is C.?

Answer 2

I'm pretty sure C. Is the correct answer is it says in parenthesis "(n-6)"

Answer 3

Thanks could you help me with another one @Agl202?

Combine like terms to simplify the expression:

7x + 3y – 2 + 6x – 1 + y2

(Points : 1)
3y3 + 13x2 – 3
y2 + 3y + 13x2 – 3
2y3 + 13x – 3
y2 + 3y + 13x – 3
