You would divide 4 from each side and that means that you would get 10/4 and that doesn’t go in evenly so you know it will be a decimal. You then solve the division and get 0.25 so that means that x=0.25

No can I please have brainliest because I have you an explanation?

A gas can is filled at the rate of 320 cubic inches per minute. The can is 10 inches long, 8 inches wide, and 12 inches high. Ho

Solution:

The gas can is filled at the rate of 320 cubic inches per minute.

The can is 10 inches long, 8 inches wide, and 12 inches high.

So volume of the can=10 in*8 in *12 in

$\text{Volume of can }=960 \ in^3\\$

Time required to fill the can $=\frac{960}{320}=3 \ minutes\\$

Hence Time required to fill the can =3 minutes.

IMPORTANT [how do you]Find sin theta if tan theta = 3/4

zvonat [6]

$\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{4}}\impliedby \textit{let's find the \underline{hypotenuse}}
\\\\\\
\textit{using the pythagorean theorem}\\\\
c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}
\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
\end{cases}
\\\\\\
c=\sqrt{3^2+4^2}\implies c=5
\\\\\\
sin(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{hypotenuse}{5}}$

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
