Answer:
You would need $18 total to buy the racks needed.
Step-by-step explanation:
First, every 20 CDs needs a new rack, so you would divide 120 by 20.
120 / 20 = 6 racks
Second, you would multiply the price ($3) of a rack by how many racks needed.
3 * 6 = $18
Answer:
<em>(-2, -6)</em>
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
<em>Hence the coordinate (x, y) is (-2, -6)</em>
