The answer is $7.00 because 56.00/8=7.00.
Hope that helps.
<em>*Because of BODMAS, 1/2x=x/2.</em>
1/2x+3/4=1
1/2x+3/4=4/4
1/2x=4/4-3/4
1/2x=1/4
x/2=1/4
x=2/4
x=1/2
Step-by-step explanation:

First, let's move the
to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:

From here, since the coefficient of the
term is
, we know the square will be
(since
it's half of
).
To complete this square, we will need to add
to both sides of the equation:



Now we can take the square root of both sides to figure out the solutions to
:


Answer: 140
Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D
