Ilya [14]

x=25

Step-by-step explanation:

2000=400√x

Step 1: Flip the equation.

400√x=2000

Step 2: Divide both sides by 400.

400√x/400=2000/400

√x=5

Step 3: Solve Square Root.

√x=5

x=52(Square both sides)

x=25

What is the center of a circle represented by the equation (x-5)2+(y+6)2=42?
Ilia_Sergeevich [38]

\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{}{ h},\stackrel{}{ k})\qquad \qquad radius=\stackrel{}{ r} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ (x-5)^2+(y+6)^2=42\implies [x-\stackrel{h}{5}]^2+[y-(\stackrel{k}{-6})]^2=(\stackrel{r}{\sqrt{42}})^2~~ \begin{cases} \stackrel{center}{(5,-6)}\\\\ \stackrel{radius}{\sqrt{42}} \end{cases}

6x+2y=8

<u>(-) x+2y=-2</u>

<u>5x=10</u>

5

x=2

x+2y=-1

2+2y=-1

<u>-</u><u>2</u><u> -</u><u>2</u>

<u>2y=-</u><u>3</u>

2

y=-3/2

Step-by-step explanation:

  1. multiply the first equation by 2 to make y equal to each other.
  2. subtract to eliminate y
  3. divide by 5 to get x
  4. take one of the equations
  5. replace x by 2 to solve for y

Let the width of table B be w, and since area of table A = area of table B, then 6 2/3 x 3 1/2 = 4 1/4 x w    [this is the required equation]
20/3 x 7/2 = 17/4 w
17/4 w = 70/3
w = 70/3 / 17/4 = 70/3 x 4/17 = 280/51 = 5 25/51
