mr. and mrs. linx both work for the same company, but they do not have the same hourly wages. Together they make $32.50 per hour

Answer:

He would at least made $18.95 dollars per hour

Step-by-step explanation:

You first have to multiply 36.50 to 35, you would get 1137.5. Since the question ask how many he earn each HOUR, you have to divide it 60, which you get 18.95 and other decimal. If it wrong, I'm sorry. I tried my best.

Answer: a) -240

<u>Step-by-step explanation:</u>

$2\sqrt{-32}\cdot 5\sqrt{-18}\\\\=2\cdot 5\sqrt{-32\cdot -18}\\\\=10\sqrt{-1\cdot 2\cdot 2\cdot 2\cdot 2\cdot 2\cdot -1\cdot 2\cdot 3\cdot 3}\\\\\\=10(-1\cdot 2\cdot 2\cdot 2\cdot 3)\\\\=10(-24)\\\\=\boxed{-240}$
