Answer:

x = 18

Step-by-step explanation:

2x + 3(4) - 1 = 47

Begin by combining your like terms

2x + 12 - 1 = 47

2x + 11 = 47

Isolate your variable (x) by using inverse operations

2x = 36

x = 18

Aloiza [94]

Answer:    

   \frac{∂z}{∂x}=\frac{(3yz-3x^{2})}{3z^{2} -3xy}

Step-by-step explanation:

Given equation is x^{3}+y^{3}+z^{3}=3xyz ………………(1)

we use derivative formula \frac{d}{dx}(x^{n})  = n x^{n-1}

\frac{d}{dx}(x^{3)}  = 3 x^{2}

\frac{d}{dx}(z^{3)}  = 3 z^{2}

And also apply 'u v' formula

\frac{d}{dx}(uv})  = u\frac{d}{dx}(v)+v\frac{d}{dx}(u)

Differentiating  equation (1) partially with respective to 'x' , we treated 'y' as constant.

(3x^{2} +0+3z^{2}\frac{∂z}{∂x}) =3y(x\frac{∂z}{∂x}+z(1))   ( here y treated as constant so the derivative of constant function is zero in addition but in multiplication the constant is keep as like 'y').

on simplification , we get

(3x^{2} +0+3z^{2}\frac{∂z}{∂x}) =(3yx\frac{∂z}{∂x}+3yz)

again simplification, we get

3z^{2}\frac{∂z}{∂x}- 3yx\frac{∂z}{∂x}=3yz-3x^{2}

taking common '\frac{∂z}{∂x} on left on side , we get

(3z^{2}- 3yx)\frac{∂z}{∂x}=3yz-3x^{2}

dividing '(3z^{2}- 3yx) on both sides, we get

\frac{∂z}{∂x}=\frac{(3yz-3x^{2})}{3z^{2} -3xy}

<u>Final answer</u>:-

\frac{∂z}{∂x}=\frac{(3yz-3x^{2})}{3z^{2} -3xy}

PLEASE SOMEONE HELP MEEEEEEEEEEEEEEEEEEEE
Sever21 [200]

Answer:

A

Step-by-step explanation:

Formula for Volume: <em>L x W x H</em>

The length of the base, is 10 in.

width is 1.7 in.

height is 20 in.

Then, you simply multiply them all by together

10 x 20 = 200

(I did these first because it is more simple)

Then, 200 x 1.7 = 340

The exponent for volume must always be ^3 because there is 3 measurements required to find the volume. So the answer is A

Hope this helps!!

Which fractions are the same value as 16 divided by-3
iragen [17]

Answer:

Not sure if this was meant to be a multi choice question, but I'll try help anyway.

As long as you times the denominator and the numerator by the same number, many fractions can be of the same value as 16/-3.

For example, a potential answer to this could be 32/-6.

If we simplify this, we still get  16/-3.

They're different fractions, but of the same value.

Hope this helps!!
