Answer:

$\boxed{\bold{x=6}}$

Step By Step Explanation:

Multiply Both Sides By 10

$\bold{4.5x\cdot \:10-7\cdot \:10=20\cdot \:10}$

Simplify

$\boxed{\bold{45x-70=200}}$

Add 70 To Both Sides

$\bold{45x-70+70=200+70}$

Simplify

$\bold{45x=270}$

Divide Both Sides By 45

$\bold{\frac{45x}{45}=\frac{270}{45}}$

Simplify

$\bold{x=6}$

Answer:

It is 0.4524 rounded simply you can say 0.45

Step-by-step explanation:

if you multiply 2/7 by 6 which is 12/42 and 1/6 times 7 which is 7/42 and add both fractions you will get 19/42 which is 0.45 you can either say the answer is 0.45 or 19/42.

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.

Tamiku [17]

You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
$V=540=\pi r^2*h= \pi r^2*15$
Then,
$r^2= \frac{540}{15 \pi }$
So, $r= \sqrt{\frac{540}{15 \pi }}$
radius is approximately 3.4cm
