Since .25*10 is 2.50 and .10*15 is 1.50 it equals $4. So the ratio is 10:15 which turns to 2:3 ratio simplified.

Let x = # of quarters // Let y = the # of dimes

25x + 10y = 400

x + y = 25

Using these two equations, we can make a system to solve. The formatting on Brainly makes it hard to write on here, so I'll just handwrite it.

Basically, the answer is 3:2.

Lelu [443]

We are given coordinates of the school located at a point (9,-1).

Library is located 5 blocks south and 4 blocks west .

According to coordinate axes, south is downward and west is on left side.

So, we need to move 5 units down of 9.

<em>5 units down of 9 would be 9-5 = 4.</em>

And then <em>4 blocks west that mean -1 -4 = -5.</em>

<h3>Therefore, coordinate of the library is located at the point (4,-5).</h3>
