Now you must plug in the ratio of games lost to games played. You know they lost 4 games and played 11, so the ratio would be 4:11.

I hope you find this helpful :)

Hi guys really need help w/ this problem will give brainllest for the first person
Vladimir [108]

Answer:

There are 6 nickels, 10 dimes and 13 quarters.

Step-by-step explanation:

number of nickels = n

number of dimes = n+4

number of quarters = (n+4)+3 = n+7

express total amount in cents $4.55 = 455 cents

express total in cents by multiplying quantities of coins by value and adding them up.

455 = 5*n + 10*(n+4) + 25*(n+7) 455 = 5n + 10n + 40 + 25n + 175 240 = 40n n = 6

so number of nickels = 6.

number of dimes = number of nickels + 4 = 6+4 =10

number of quarters = number of dimes + 3 = 10+3 = 13

There are 6 nickels, 10 dimes and 13 quarters.
