Answer:

$\Delta s = \frac{71\pi}{60}\cdot r$

Step-by-step explanation:

Let r be the radius of the circle, the measure of the arc is equal to:

$\Delta s = \frac{213^{\circ}}{360^{\circ}}\cdot 2\pi \cdot r$

$\Delta s = \frac{71\pi}{60}\cdot r$

Answer:

$x=5.250$

Step-by-step explanation:

We have been given an equation $4x-3=18$ . We are asked to solve our given equation.

First of all, we will add 3 to both sides of our equation.

$4x-3+3=18+3$

$4x=21$

Now, we will divide both sides of our equation by 4.

$\frac{4x}{4}=\frac{21}{4}$

$x=5.25$

Upon rounding our answer to nearest thousandth (3 places after decimal) we will get,

$x=5.250$

Therefore, the solution for our given equation is $x=5.250$ .

Dale currently has $599 in his savings account. Prior to getting paid, he had $230 in his savings account. How much was Dale’s p

Hi!

So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599.

Take the parts I put in bold, and write the equation.
$230 + x = $599

Now we need to find x.

Whatever we do to the equation, we do it to both sides.
Our goal is to isolate x on one side.

Subtract 230 from both sides.
$230 - $230 + x = $599 - $230
x = $369

The answer is A. $230 + x = $599 x = $369

Hope this helps! :)
