Amanda [17]

Answer:

$\huge\boxed{x=1,\ y=2\to(1,\ 2)}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}3x+4y=11\\x-2y=-3&\text{multiply both sides by (-3)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}3x+4y=11\\-3x+6y=9\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\ \ \ \ 10y=20\qquad\text{divide both sides by 10}\\.\qquad\qquad\boxed{y=2}\\\\\text{subtitute it to the second equation:}\\x-2(2)=-3\\x-4=-3\qquad\text{add 4 to both sides}\\\boxed{x=1}$

What is 4/5 of 12 inches

Reptile [31]

To find the answer to this problem, you would multiply 4/5 to 12 (or 12/1). And you would end up with 48/5, and when you divide this out, you would end up with 9.6. So 9.6 should be your final answer.
Hope this helped! :)
