What is 3x + x - 5 = 2(x-2) ?<br> Show each step

prohojiy [21]

Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5
Hope this helped!

What is the area of a 30 degree sector of a circle with area 96 pi meters ^2?

iren2701 [21]

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
-----\\
A=96\pi 
\end{cases}\implies 96\pi =\pi r^2
\\\\\\
\cfrac{96\underline{\pi }}{\underline{\pi }}=r^2\implies 96=r^2\implies \boxed{\sqrt{96}=r}\\\\
-------------------------------$

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}~~
\begin{cases}
r=radius\\
\theta = angle~in\\
\qquad degrees\\
------\\
\theta =30\\
r=\boxed{\sqrt{96}}
\end{cases}\implies A=\cfrac{(30)(\pi )(\sqrt{96})^2}{360}
\\\\\\
A=\cfrac{(30)(\pi )(96)}{360}\implies A=8\pi$
