The answer is (x, y) = (-1, 4) hope this helped
Answer:
Step-by-step explanation:
Let the width be x
- Then the length is 3x + 2
- Perimeter = 66
<u>Perimeter formula</u>
<u>Substitute values</u>
- 66 = 2(3x + 2 + x)
- 33 = 4x + 2
- 4x = 31
- x = 31/4
- x = 7.75
<u>The length is:</u>
+30 min = 5pm, then +60 min = 6pm, then + 15 min = 6:15pm
30min+60min+15min
90min+15min
105 minutes
105-60=45 so 1 hour and 45 minutes
Answer:
7: (3,9) 8:(-2,1) 6: (2,10)
Step-by-step explanation:
7) 2x+3=-2x+15
x=3
y=2(3)+3
y=6+3
y=9
8)x= -1(1+2y)/3
-4-2y=-6
y=1
x=-2(1+2(1))/3
x=-2
6)2x-16=-12
x=2
y=2+8
y=10
