Answer:
A
Step-by-step explanation:
x=6.28111...
100 x=628.111...
1000x=6281.111...
subtract
900x=5653
x=5653/900
density of iodine=785×5653/900≈4930.672222...
Here 2 is repeating .

Answer:
22
Step-by-step explanation:
This is a right angle so the sum of those would be equal to 90 degrees
x + 7 + 3x - 5 = 90 add like terms
4x + 2 = 90 subtract 2 from both sides
4x = 88 divide both sides by 4
x = 22
The solution to the given equation is -87/45
<h3>Product of expressions</h3>
Given the following expression that represents the word problem as;
-1/5 * 3 - 12(1/3)^2
Using the PEMDAS rule, the parenthesis and exponent will come first to have;
-1/5 * 3 - 12(1/3)^2 = -1/5 * 3 - 12(1/9)
Then multiplication
-1/5 * 3 - 12(1/9) =. -3/5 - 12/9
Find the difference
-1/5 * 3 - 12(1/9) = -27-60/45
-1/5 * 3 - 12(1/9) = -87/45
Hence the solution to the given equation is -87/45
