Answer:
x = 7/ 9
Step-by-step explanation:
Let x = 0.777777777777 ... ... ... ... ...........(A)
then 10 x = 7.7777777777777 ... ... ... ... ............(B)
Subtracting (A) from (B)
9 x = 7 and x = 7 /9

7 over 9 so 7/9
x=51
For subsets A={1,2},B={2,3},C={1,2 5} of U = {1, 2, 3, 4, 5}.
A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.
Step-By-Step Explanation:
U = {1, 2, 3, 4, 5}.
A={1,2}
B={2,3}
C={1,2 5}
For the Left Hand Side
B-C={3}
A ∪ (B − C)= {1,2} ∪ {3} ={1,2,3}
Likewise, the Right Hand Side:
(A ∪ B)={1,2,3}
(A ∪ C)={1,2,5}
(A ∪ B)- (A ∪ C)= {1,2,3}-{1,2,5}={3}
Since, {1,2,3} ≠ {3}, A ∪ (B − C) = (A ∪ B) − (A ∪ C) does not hold.
Gradient=¾
Write the equation in slope-intercept form y=mx+c
3x-4y=24
-4y=24-3x
y=24/-4-3x/-4
y=-6+¾x
y=¾x-6
The gradient is therefore ¾
The y-intercept of the line occurs at(0,-6)
The x-intercept of the line occurs at(8,0)
Finding the midpoint of the two intercepts
{(x1+x2)/2,(y1+y2)/2}
M={0+8/2,(-6+0/2)}
M={8/2,-6/2}
M=(4,-3)
As you can see, the other information was not required to solve it
