Answer: a=8 and b=1
Step-by-step explanation:
If x represents the paddling speed, and y represents the speed of the current.
Then Relative speed in upstream =x-y
Relative time in downstream=x-y
When she paddles upstream then distance covered by her=
⇒8=(x-y)2 or 2(x-y)=8
Thus we get, a=1
When she paddles downstream then distance covered by her=
⇒8=(x+y)1 or 1(x+y)=8
Thus we get b=1
Answer:
5 pounds and 8 ounces of seed per one acre.
Step-by-step explanation:
We have our two values, 44 pounds and 8 acres.
It also says it takes 44 pounds of seed for every 8 acres of farmland.
So to get the value of how much seed per one acre we need, we divide 44 by 8.
Doing so yields us 5.5 pounds, which can be converted to 5 pounds and 8 ounces. (remember 16 ounces is 1 pound)
1) 0.0 + 5.5 = 5.5
2) 5.5 + 5.5 = 11.0
3) 11.0 + 5.5 = 16.5
4) 16.5 + 5.5 = 22.0
5) 22.0 + 5.5 = 27.5
6) 27.5 + 5.5 = 33.0
7) 33.0 + 5.5 = 38.5
8) 38.5 + 5.5 = 44.0
Answer:
the answer is 267.9 cubic inches
Step-by-step explanation:
Step-by-step explanation:
The answer is even function.
X-4/2x=3x/2x-1 (invert the bottom and then multiply)
<span>x-4 (2x+3x/2x-1) ( the 2x's cancel) </span>
<span>x-4 (3x/-1) </span>
<span>x-4 (-3x) (expand) </span>
<span>-3x^2 + 12x=0 </span>
<span>-3x^2= -12x (bring 12x to other side making it negative) </span>
<span>-3x^2/3x= -12x/-3x (divide both sides by -3x) </span>
<span>x=4 </span>
<span>Hope that helps</span>
