Answer:
y = -4, x = -9
Step-by-step explanation:
System: -2x + 5y = -2, x - 3y = 3
Multiply the second equation: 2x - 6y = 6
Elimination:
-2x + 5y = -2
<u>+ 2x - 6y = 6</u>
- y = 4 --> y = - 4
Plug in: x - 3(-4) = 3
x + 12 = 3
x = -9
The solution would be like this for this specific problem:
12! = 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
= 479,001,600

there are 479,001,600 <span>different group of students that can show up
for a seminar with an enrollment of 12.</span></span>
- Area of shaded region = 2571.66 in²
Radius of smaller circle = 25 in
Radius of larger circle = 25 + 13 = 38 in
Area of ring : Area of larger circle - Area of smaller circle
Factor out of .
I believe that's the correct answer.
Answer:one yard costs $15 (x=15)
Step-by-step explanation:
300-60=240. So, 16 yards=$240
16x=240
240/16=15
X=15 (one yard costs $15)
