c = -6

a = -3/2

m = -24/5

Step-by-step explanation:

<h2>#1</h2>

5(c + 2) = -20

5c + 10 = -20

5c = -20 - 10

5c = -30

<u>c = -6</u>

<h2>#2</h2>

12a + 5 - 8a = -1

4a + 5 = -1

4a = -1 - 5

4a = -6

a = (-6)/4

<u>a = -3/2</u>

<h2>#3</h2>

m - 3 - 6m = -27

-5m - 3 = -27 → (times -1)

5m + 3 = 27

5m = 27 - 3

5m = 24

<u>m = 24/5</u>

The pool is located at (0,0) to get to your house from the pool you walk three blocks west and one block north what ordered pair
ira [324]

Answer:

(-3, 1) quadrant II (2)

Step-by-step explanation:

An image of the coordinate plane is show.  The quadrants start at the top right and move around in the counter-clockwise direction.  The x-axis is horizontal (side to side) and y-axis is vertical (up and down).  Starting at the origin of the coordinate plane (0, 0) and going three blocks west (left) would put you at -3 on the x-axis.  If you then proceed to go north (up) +1, you would now be at point (-3, 1) which is a (-x, +y)  or in quadrant II.
