It cost $156.40 because 20% of 195.50 is $39.10 so you subtract that from the 195.50.
The first is a. you can rewrite it

the second is d. the only common factor between 20 and 40 that can be taken out is the 4 which becomes a 2, but inside the square roots there is still a 5 and 10, which cannot be combined
the third is c.

the fourth is d.
add 3 to both sides

then square both sides

then divide both sides by 2, x=50
Answer:

Step-by-step explanation:
Given
Let the number be x
So:

Required
Using trial and improvement, find x
This implies that we keep guessing the values of x until we get a value that match the equation.
Let

So, we have:


Take the square root of 625



Let

So, we have:


Take the square root of 729



At this point, we can conclude that x is approximately 729 because

So:
