Answer:
Fraction of fence = 2/3 which is approximately 0.67
Explanation:
We know that he finishes 1/3 of the fence in 1/2 an hour. To know the fraction he can finish in one hour, we will simply use cross multiplication as follows:
1/3 of the fence ...................> 1/2 an hour
?? of the fence ....................> 1 hour
Fraction of the fence = (1/3 * 1) / (1/2)
Fraction of fence = 2/3 which is approximately 0.67
Hope this helps :)
Solve the equation. Isolate the variable, x.
Note the equal sign, what you do to one side, you do to the other.
First, subtract 8 and 10x from both sides:
2x (-10x) + 8 (-8) = 12 (-8) + 10x (-10x)
2x - 10x = 12 - 8
Simplify. Combine like terms:
(2x - 10x) = (12 - 8)
-8x = 4
Isolate the variable, x. Divide -8 from both sides:
(-8x)/-8 = (4)/-8
x = -(4/8)
Simplify:
x = -1/2
-1/2 is your answer for x.

Answer:
The difference between online school and in person school is that online is online and inperson is in person.
Step-by-step explanation:
At the point when Hannah takes her first sweet from the sack, there is a 6/n chance it is orange.
This is because that there are 6 orange desserts and n desserts altogether.
When Hannah takes out her second sweet, there is a 5/(n-1) chance that it is orange.
This is because there are just 5 orange desserts let alone for an aggregate of n-1 desserts.
The possibility of getting two orange desserts in succession is the main likelihood increased by the second one: 6/n x 5/n–1
The question lets us know that the shot of Hannah getting two orange desserts is 1/3.
So: 6/n x 5/n–1 = 1/3
Now, rearrange this problem.
(6x5)/n(n-1) = 1/3
This gets to be:
30/(n² – n) = 1/3
Times by 3 on both sides:
90/(n² – n) = 1
What's more, doing likewise with (n² – n):
So (n² – n) = 90
Our answer is: n² – n – 90 = 0
