The ratio of nickels to dimes in a piggy bank is 7 : 11. If there are a total of 90 nickels and dimes in the piggy bank, how many of them would you expect to be dimes?

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

i think the amount would be $140.62
