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.

Find m<DCV and m<VBD

max2010maxim [7]

9514 1404 393

Answer:

m∠DCV = 50°
m∠VBD = 50°

Step-by-step explanation:

Arc DV is 100°, so any inscribed angle that intercepts that arc will have a measure that is half of 100°, or 50°.

Inscribed angles DCV and VBD both intercept arc DV, so both are 50°.

Answer:

figure skates will be $1 cheaper.

Explanation:

given equation:

to rent figure skates : f(x) = 1.50x + 2

to rent hockey skates : h(x) = 2x +1.5

solve for rent of figure skates:

f(x) = 1.50x + 2.00

f(3) = 1.50(3) + 2.00

f(3) = 6.5

solve for rent of hockey skates:

h(x) = 2x + 1.5

h(3) = 2(3) +1.5

h(3) = 7.5

cheaper - figure skates than hockey skates:

$7.5 - $6.5
