Simplifying for y we get ![y=-\sqrt[3]{\frac{(7+x)}{3}}](https://tex.z-dn.net/?f=y%3D-%5Csqrt%5B3%5D%7B%5Cfrac%7B%287%2Bx%29%7D%7B3%7D%7D)
Step-by-step explanation:
We need to solve for the value of y

Taking -3 common on right side of equation

Dividing both sides of equation by 9


Taking cube root on both sides:
![\sqrt[3]{y}=-\sqrt[3]{\frac{(7+x)}{3}}\\ y=-\sqrt[3]{\frac{(7+x)}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%7D%3D-%5Csqrt%5B3%5D%7B%5Cfrac%7B%287%2Bx%29%7D%7B3%7D%7D%5C%5C%20y%3D-%5Csqrt%5B3%5D%7B%5Cfrac%7B%287%2Bx%29%7D%7B3%7D%7D)
So, Simplifying for y we get ![y=-\sqrt[3]{\frac{(7+x)}{3}}](https://tex.z-dn.net/?f=y%3D-%5Csqrt%5B3%5D%7B%5Cfrac%7B%287%2Bx%29%7D%7B3%7D%7D)

Answer
11/6
182/99
explanation:
Explanation:
In case you have not encountered the notation, note that a repeating pattern of digits can be indicated by drawing a bar above it.
The probability of choosing a correct answer = 1/5
The probability of choosing a wrong answer = 4/5
Scores received on correct answer = +3
Scores received on wrong answer = -1
Scores on blank answer = 0
The average scores, in long run will be equal to the expected value. The expected value E, in this case will be:
Thus, in long run, the student will score -0.2 points on average.
Hi!
Let's write the equation in number form first.
7 over 8
7/8
minus 1
7/8 - 1
over x
7/8 - 1/x
equals 3
7/8 - 1/x = 3
over 4
7/8 - 1/x = 3/4
Now to find the value, let's put each option as the value for x.
A. x = 1
7/8 - 1/1 = 3/4
7/8 - 1 = 3/4
0.875 - 1 = 0.75
-0.125 = 0.75
This is wrong.
B. x = 2
7/8 - 1/2 = 3/4
7/8 - 0.5 = 3/4
0.875 - 0.5 = 0.75
0.375 = 0.75
This is wrong.
C. x = 4
7/8 - 1/4 = 3/4
7/8 - 0.25 = 3/4
0.875 - 0.25 = 0.75
0.625 = 0.75
This is wrong.
D. x = 8
7/8 - 1/8 = 3/4
7/8 - 0.125 = 3/4
0.875 - 0.125 = 0.75
0.75 = 0.75
This is correct!
The answer is d. x = 8
Hope this helps! :)
