Answer: x=2
Step-by-step explanation:
Expand.
32−8x=7x+2
Add 8x to both sides.
32=7x+2+8x
Simplify 7x+2+8x7x+2+8x to 15x+215x+2.
32=15x+2
Subtract 22 from both sides.
32−2=15x
Simplify 32−2 to 30.
30=15x
Divide both sides by 15.
30/15=x
Simplify 30/15 to 2
2=x
Switch sides.
x=2
30 divided by 6 is 5, 60 divided by 6 is 10. 5*10 = 50
50 is your answer
Answer:
25%, the same rate of vegetation increases
Answer:
The probability that a student earns a grade of A is 1/7.
Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:
P(E) = n(E) / n(S)
As the total number of students = n(S) = 35
Students getting the grade A = n(E) = 5
So, the probability that a student earns a grade of A:
P(E) = n(E) / n(S)
= 5/35
= 1/7
Hence, the probability that a student earns a grade of A is 1/7.

The perimeter of the square is: 76.4 meters
Step-by-step explanation:
We have to find the side of square to find the perimeter
So
Area = A = ![364.81\ m^2](https://tex.z-dn.net/?f=364.81%5C%20m%5E2)
Let s be the side of the square
then
![A = s^2](https://tex.z-dn.net/?f=A%20%3D%20s%5E2)
Putting the value of area
![364.81 = s^2](https://tex.z-dn.net/?f=364.81%20%3D%20s%5E2)
Taking square root on both sides
![\sqrt{s^2} = \sqrt{364.81}\\s = 19.1\ m](https://tex.z-dn.net/?f=%5Csqrt%7Bs%5E2%7D%20%3D%20%5Csqrt%7B364.81%7D%5C%5Cs%20%3D%2019.1%5C%20m)
The side of square is 19.1 meters
Now
Let P be the perimeter
Then
![P = 4s\\= 4 * 19.1\\=76.4\ m](https://tex.z-dn.net/?f=P%20%3D%204s%5C%5C%3D%204%20%2A%2019.1%5C%5C%3D76.4%5C%20m)
The perimeter of the square is: 76.4 meters
