Answer:

4 is your value for m.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Do the opposite of PEMDAS.

First, add 5 & m to both sides:

2m (+ m) - 5 (+ 5) = - m (+ m) + 7 (+ 5)

2m + m = 7 + 5

Simplify. Combine like terms:

3m = 12

Isolate the variable, m. Divide 3 from both sides:

(3m)/3 = (12)/3

m = 12/3

m = 4

m = 4 is your answer.

What's 2/4 x 1/3? And pls provide work on how u got the answer.

igomit [66]

Just multiply the top number by the top number and the bottom numbers by the bottom numbers so

2/4 times 1/3=(2 times 1)/(4 times 3)=2/12

so to simplify, we find the ones exg 4/8=1/2 because 1/2 times 4/4=4/8 and 4/4 cancels out so

2/12=2/2 times 1/6
=1/6

Find x Plz help me !!!

mel-nik [20]

Answer:

$\Huge\boxed{x=33.2}$

Step-by-step explanation:

Hello there!

We can solve for x using law of sines

As we can see in the image a side length divided by sin ( its opposite angle) = a different side length divided by sin ( its opposite angle)

So we can use this equation to solve for x

$\frac{21}{sin(35)} =\frac{x}{sin(65)}$

Our objective is to isolate the variable using inverse operations so to get rid of sin (65) we multiply each side by sin (65)

$\frac{x}{sin(65)} sin(65)=x\\\\\frac{21}{sin(35)} sin(65)=\frac{21sin(65)}{sin(35)}$

we're left with

$x=\frac{21sin(65)}{sin(35)}\\x=33.18208755$

assuming we have to round the answer would be 33.18 or 33.2

Find the volume of the cone shown below.

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

The formula for volume of cone is $V=\frac{1}{3}\pi r^2 h$

Where

V is the volume

r is the radius of the circular base

h is the height of the cone

In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):

$V=\frac{1}{3}\pi (9)^2(12)\\=324 \pi$

correct answer is D
