Answer: the second option !!!
Answer:
C≈61.89
C=3830.37
Step-by-step explanation:
A≈615.75
The answer is C: 
Starting with the given formula for the area, A = 1/2hb, the first step is to isolate h by using the multiplicative inverse of b, which is
on both sides of the equation:

The result will be:

The last step is to use the multiplicative inverse of
, which is 2 or
to further isolate the variable <em>h </em>:

The formula for h will be:
which is the option C in your question.
Answer:
0.132
Step-by-step explanation:
if 1kg of chees cost 6.60 100g cost 0.0660 So if 0.0660 multiplied by 2
= 0.132
Subtract 9 from each side of the equation. so you would get 1<x. meaning that any number larger then 1 would correctly solve the equation.
