Bodhi has a collection of 175 dimes and nickels. the collection is worth $13.30. which equation can be used to find n, the number of nickels in the collection?

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=13.30.

17.5-0.1n+0.05n= 13.30 (By distributing property)

17.5-0.05n=13.30 (Combine the like terms)

-0.05n=13.30-17.5 (Subtract 17.5 from each sides).

-0.05n=-4.2

-0.05n/-0.05=-4.2/-0.05 ( Divide each sides by -0.05)

n=84

So, there is 84 coins in the collection.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
