Answer:
no Solution
Step-by-step explanation:
-12x-12y=4\\ 3x+3y=0
12x-12y=4
add 12y to both sides
12x-12y+12y=4+12y
divid both sides by -12
\frac{-12x}{-12}=\frac{4}{-12}+\frac{12y}{-12}
simplfy
x=-\frac{1+3y}{3}
\mathrm{Substitute\:}x=-\frac{1+3y}{3}
\begin{bmatrix}3\left(-\frac{1+3y}{3}\right)+3y=0\end{bmatrix}
\begin{bmatrix}-1=0\end{bmatrix}
Its 72 degrees i just did this one plato
18 x 3 = 54. So the correct answer is D. 54 pounds.
X=15 and Y=?
X=30 and Y=6
By rule of three
15x6/30 = 3
The answer is Y=3
So the first one, 1.2 >11/5. and the second one 1/3> 1/2
