Answer:
Option C: (5/4)x - 2 = (3/2)x - 4
Step-by-step explanation:
A) (5/2)x + (7/2) = (3/4)x + 14
Multiply through by 4 to get;
10x + 14 = 3x + 56
10x - 3x = 56 - 14
7x = 42
x = 42/7
x = 6
B) (5/4)x - 9 = (3/2)x - 12
Multiply through by 4 to get;
5x - 36 = 6x - 48
6x - 5x = 48 - 36
x = 12
C) (5/4)x - 2 = (3/2)x - 4
Multiply through by 4 to get;
5x - 8 = 6x - 16
6x - 5x = 16 - 8
x = 8
D) (5/2)x - 7 = (3/4)x + 14
Multiply through by 4 to get;
10x - 28 = 3x + 56
10x - 3x = 56 + 28
7x = 84
x = 84/7
x = 12

Answer:
Option C is correct.........
Answer:
7
Step-by-step explanation:
Given that there are 5 number cards.
They are 2,5,7,8,9
Total of all numbers in the cards = 2+5+7+8+9= 31
One card is removed say with number x.
Now sum new would be =31-x .. i
Average of remaining 4 cards = 6
So sum of remaining 4 cards = 6(4) = 24 ... ii
i and ii represent the sum of remaining 4 cards. Hence they should be equal
31-x =24
Subtract 31 from both sides to get
-x=-7
Or x =7
