What equation can be used to find n, the number of nickels in the collection ?

Answers

Given, Bodhi has a collection of 175 dimes and nickel. If she has n numbers of nickel. Then,

The number of dimes coin= 175-n.

The collection is worth $13.30.

1 nickel is worth five cents. So, n nickel will worth 0.05n.

Similarly 1 dime is worth 10 cents. So, 175-n dimes will worth 0.1(175-n).

Since the total worth is $13.30. So, we can set the equation as follows:

0.1(175-n)+0.05n=13.13.

Hence, the last option is the correct choice.

8r-5>6r-1or 4+4r<3r-3

Answers

For the first inequality you add 5 to each to get 8r>6r+4, then subtract 6r from each to get 2r>4 and divide by 2 so for that part r>2... For the second equation subtract 4 from each side to get 4r<3r-7, then subtract 3r to get r<-7... When you put it all together you get 2
