To do this you will take the mass of the sack which is 45g.

Divide this amount by the number of nickels in the sack which is 9.

45 \div 9 = 5

So the mass of one nickel is 5g.

Hello there!

9 nickels = 45g

1 nickel = ?

Then cross multiply that

45 * 1 = 9 * x

45 = 9x

x = 45/9

x = 5

As always, it is my pleasure helping students like you!

Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no
aliina [53]

9514 1404 393

Answer:

 2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...

  (2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

__

Three solutions are shown:

  (x, y) = (2, 9), (3, 10), (4, 11)
