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

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)

HELP PLEASE!!!!!! I need help Urgent Help

This is just a porportion. So if 250 meters is 1 meter than: 250/1

And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x

Set them equal to each other 250/1=212/x

Cross multiply: 212=250x

Divide to find x: 212/250=x
x=212/250
x=0.848

So the height of the model, to the nearest 10th would be 0.8 meters.
