Answer:

Step-by-step explanation:

b and c are part of an 180 degrees angle.

You already have a 90 degrees angle

180-90=90

And since there are 2 angles

90/2=45

And b and c are vertical angles

56. Because C is a supplementary angles and supplementary angles combine to make 180 degree angles which are straight lines in any direction like vertical, horizontal, or diagonal. So if we take the 124 next to the C and subtract 124 from 180, you get 56.

I'm really not sure how to go about solving this algebraic equation, please help! .513 = (2x)^2 / (.05-x)

LiRa [457]

Let's set it up like this:
$0.513=\frac{\left(2x\right)^2}{\left(0.05-x\right)}$
Multiply both sides by $0.05-x$
$0.513\left(0.05-x\right)=\frac{\left(2x\right)^2}{0.05-x}\left(0.05-x\right)$
$0.513\left(0.05-x\right)=4x^2$
We are then going to use the distributive property. Since we also know that the opposite of an number that is squared is the square root, we can also apply that. We would be left with something like this:
$x=-\frac{0.513+\sqrt{0.673569}}{8},\:x=\frac{\sqrt{0.673569}-0.513}{8}$
The variable $x$ can be both positive or negative.
We have found successfully our answer.

Which answer describes the calculations that could be used to solve this problem?

D. Since we know that 1 ticket = $8 we would multiply to figure out how much 7 tickets were. (7x$8). And to figure out his change you would subtract the ticket amount from $100 :) Hope this helps
