$\huge\text{Hey there!}$

$\mathsf{13x = 6}$

$\huge\textsf{DIVIDE 13 to BOTH SIDES}$

$\mathsf{\dfrac{13x}{13}=\dfrac{6}{13}}$

$\rm{CANCEL \ out: \dfrac{13}{13} \ because \ that \ gives \ you \ 1}$

$\rm{KEEP: \dfrac{6}{13} \ because \ that \ gives \ you \ the \ value \ of \ x}$

$\boxed{\boxed{\mathsf {Answer: x = \bf \dfrac{6}{13}}}}\huge\checkmark$

$\boxed{\textsf{or you could say \boxed{\mathsf{x = \underline{\bf 0.461538}}} they both equal to the same thing}}\huge\checkmark$

Find derivative of y=(-3x^5+1)^3

sattari [20]

Use the chain rule:

$\frac{\mathrm dy}{\mathrm dx}=3(-3x^5+1)^2\frac{\mathrm d[-3x^5+1]}{\mathrm dx}=3(-3x^5+1)^2(-15x^4)=\boxed{-45x^4(1-3x^5)^2}$

3.75x = 3<br> how to do this, please help.

Travka [436]

Answer:

0.8

Step-by-step explanation:

you divide both sides by 3.75 (because its multiplied) so the 3.75 connected to the x cancels out and your left with x on the left and 3 over 3.75 equals 0.8 so its x = 0.8

Compare the surface area-to-volume ratios of the moon and mars. express your answer using two significant figures.

antoniya [11.8K]

we know that

For a spherical planet of radius r, the volume V and the surface area SA is equal to

$V=\frac{4}{3} *\pi *r^{3} \\ \\ SA=4*\pi *r^{2}$

The
ratio of these two quantities may be written as

$SAV =\frac{(4*\pi*r^{2})}{(\frac{4}{3}*\pi*r^{3})} \\ \\ SAV =\frac{3}{r}$

we know

$rMoon=1,738Km\\ rMars=3,397 Km$

$\frac{SAV Moon}{SAV Mars} =\frac{3}{rMoon} *\frac{rMars}{3} \\ \\ \frac{SAV Moon}{SAV Mars} =\frac{rMars}{rMoon} \\ \\ \frac{SAV Moon}{SAV Mars} =\frac{3,397}{1,738} \\ \\ \frac{SAV Moon}{SAV Mars} =1.9545$

therefore

the answer is

$1.9$
