6x-1 because you combine like terms 4x+2x=6x and then -4+3=-1

That will be 2x-1 because
(4x-2x)+(-4+3)=
2x-1

The addition sign would turn to subtract because of the reciprocal sign. Reciprocal is a sign that switch base on your sign of negative and positive.

What is the length of the radius, r? 6 cm 18 cm 36 cm 72 cm.

Rus_ich [418]

The length of the radius of circle o is 18 cm.

<h2></h2><h2>Given that</h2>

Circle o has a circumference of 36π cm.

<h3>We have to determine</h3>

What is the length of the radius, r?

<h3>According to the question</h3>

Circle o has a circumference of 36π cm.

The length of the radius of the circle is determined by the following formula;

$\rm Circumference = 2\pi r$

Substitute all the values in the formula;

$\rm Circumference = 2\pi r\\
\\
36\pi =2\pi r\\
\\
r = \dfrac{36\pi }{2\pi }\\
\\
r = 18 \ cm$

Hence, the length of the radius of circle o is 18 cm.

I'LL GIVE YOU BRAINIEST!<br> 1 1/5 · x/3 = 9/10 solve for x

joja [24]

$\huge\text{Hey there!}$

$\huge\textbf{Equation:}$

$\mathbf{1 \dfrac{1}{5} \times \dfrac{x}{3} = \dfrac{9}{10}}$

$\huge\textbf{Solve:}$

$\mathbf{1 \dfrac{1}{5} \times \dfrac{x}{3} = \dfrac{9}{10}}$

$\mathbf{\rightarrow \dfrac{1\times5+1}{5} \times \dfrac{x}{3} = \dfrac{9}{10}}$

$\mathbf{\rightarrow \dfrac{5 + 1}{5} \times \dfrac{x}{3} = \dfrac{9}{10}}$

$\mathbf{\rightarrow \dfrac{6}{5} \times \dfrac{x}{3} = \dfrac{9}{10}}$

$\huge\textbf{Simplify it:}$

$\mathbf{\rightarrow \dfrac{2}{5}x = \dfrac{9}{10}}$

$\huge\textbf{Multiply \boxed{\bf \dfrac{5}{2}} to both sides:}$

$\mathbf{\rightarrow \dfrac{5}{2}\times \dfrac{2}{5}x = \dfrac{5}{2}\times \dfrac{9}{10}}$

$\huge\textbf{Simplify it:}$

$\mathbf{\rightarrow x = \dfrac{5}{2}\times \dfrac{9}{10}}$

$\mathbf{\rightarrow x = \dfrac{5\times9}{2\times10}}$

$\mathbf{\rightarrow x = \dfrac{45}{20}}$

$\mathbf{\rightarrow x = \dfrac{45\div5}{20\div5}}$

$\mathbf{\rightarrow x = \dfrac{9}{4}}$

$\mathbf{x \approx 2 \dfrac{1}{4}}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{x = }\frak{2 \dfrac{1}{4}}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
