Hi,
2.
5(3+2x) = 10x - 4
15 + 10x = 10x - 4
10x - 10x = - 4 - 15
0 = -19
In other word there is no solution here, code G
3.
x+5 = (3x+13) / 2
x+5 = (3/2)x + 13/2
x - (3/2)x = 13/2 - 5
x(1-3/2) = 13/2 - 10/2
x(2/2 - 3/2) = 3/2
(-1/2)x = 3/2
x = (3/2) / (-1/2)
x = (3/2) * (-2)
x = (-6/2)
x= -3
code : D
Good Luck :)
The graph is shown in the attached image.
The probability that the digits display a palindrome = 19/240 Ans.
As we know the total no. of possible hours = 12
Total number of possible minutes= 60
Therefore, total no. of possible times that can be shown are = 12
Since total no. of Palindromes possible per hour for the nine hours 1 through 9 = 6
No. of palindromes per hour from 10 through 12 = 1
Therefore, total no of palindromes = (6*9) + 3 = 57
Probability that the digits display a palindrome = 57/720 = 19/240
