Answer:
Option 3 - 0 point 5.
Step-by-step explanation:
Given : Decimal equivalent of 5 over 9.
To find : Use long division to determine the decimal?
Solution :
We have to divide 5 by 9,
Step 1 - Divide 5 by 9 as it is not divisible put a decimal and 0 after 5,
Step 2 - Now, divide 50 by 9 the quotient is 5 and remainder is 5.
Step 3 - Again put 0 and divide the number repeat the process until the remainder is not zero.

So, 
Approximately, 
So, Option 3 is correct.
Refer the attached figure for calculation.
Answer:
54
Step-by-step explanation:
4x+7=18
subtracting 7 from both side of the equation
4x+7- 7=18 - 7
4x = 11
to find value of x , we divide both side of the equation by 4
4x/4 = 11/4 = 2.75
x = 2.75
now we plug in the found value of x = 2.75 in place of x in equation 12x+21
12*2.75 + 21 = 33 + 21 = 54
Thus, answer is 54
