Answer: Yes
Step-by-step explanation:
First multiply the first equation by three to get 3x+12y=69
Then subtract 12y from both sides of the second equation
Then add the first system and the second like this:
Because 0≠70, the system has no solutions
Answer:
3 times 5 = 15 and 5 times 5 = 25. 15 plus 25 = 40
Step-by-step explanation:
Step-by-step explanation:
- blue one ====> 3x+16 =9x+4 ( alternate angles)
>9x-3x=16-4
>6x=12
>x=2.
- white one ====> 10x-2=9x+5 (corresponding angle)
>10x-9x=5+2
>x=7.
- green one ====>8x+10=6x+30(vertically opposite angle)
>8x-6x=30-10
>2x=20
>x=10.
hope this helps you.
The width is 20, and there are two sides that are the width.
So in doing the width he's already used 20 + 20 = 40 feet of fencing.
200 - 40 = 160
We have 160 left for the length, and there are also two sides for the length, so we divide by 2.
160 / 2 = 80
So the length of the pen is 80 feet.
Is the question 9.75x10^4 ???
