Witch is the warmer temperature -9°F or -7°F​
oksano4ka [1.4K]

Answer:

-7°F

Step-by-step explanation:

At first, you might think that the answer is -9 because 9 > 7, right? Actually, the "rules" for numbers are switched when you are dealing with negative numbers. Therefore, -7 > -9 so -7°F is the correct answer.

What is the solution set for the equation 2|-3n| + 10 = 50<br><br> I
Aleks04 [339]

Answer:

n=-\frac{20}{3}\quad \mathrm{or}\quad \:n=\frac{20}{3}

Step-by-step explanation:

2\left|-3n\right|+10=50\\\\\mathrm{Subtract\:}10\mathrm{\:from\:both\:sides}\\\\2\left|-3n\right|+10-10=50-10\\\\Simplify\\\\2\left|-3n\right|=40\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\\\frac{2\left|-3n\right|}{2}=\frac{40}{2}\\\\Simplify\\\\\left|-3n\right|=20\\\\\mathrm{Apply\:absolute\:rule}:\\\quad \mathrm{If}\:|u|\:=\:a,\:a>0\:\mathrm{then}\:u\:=\:a\:\quad \mathrm{or}\quad \:u\:=\:-a\\

-3n=-20\quad \mathrm{or}\quad \:-3n=20\\\\-3n=-20\quad :\quad n=\frac{20}{3}\\\\-3n=20\quad :\quad n=-\frac{20}{3}\\\\n=-\frac{20}{3}\quad \mathrm{or}\quad \:n=\frac{20}{3}

A milk container’s capacity is one gallon. How many cups would be equal?*
bonufazy [111]
This is a pretty easy problem. In order to get the answer to this problem, you just have to convert one gallon into cups. For this, I do suggest that you review your measurement table since the answer is already there for you to take a look at. However, for the sake of making things faster, I will give the answer here. Basically, 1 gallon will equal to 16 US cups. So to conclude it, the milk container's capacity is actually 16 cups.
