In A City, The Distance Between The Library And The Police Station Is 3 Miles Less Than Twice The Distance Between The Police Station And The Fire Sta

In a city, the distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station. The distance between the library and the police station is 5 miles. How far apart are the police station and the fire station?

 

Answer:4 miles. (Never forget about the unit)

Step-by-step explanation:write everything first.

2x(twice the distance)

-3(three less than?)

5 miles.(given distance from library to police station)

The mathematical phrase less than along with subtracted from, etc means inverted. Ex. 5 less than 8 is 8-5

Do the Inverse operation of subtraction and that is addition

5+3=8

Then do the inverse operation of multiplication which is division

8÷2=4

Its like algebra really but its simple. I hope I wasnt late in answering

What Is The Big One?

What is the Big One?   The Big One is a descriptive term used as a strong and disastrous earthquake scenario. It is magnitude 8 or higher. Here in our country, It is said that the West Valley Fault could move to Metro Manila which is considered to cause serious damage so others called it The Big One. Experts say the West Valley Fault goes through in the provinces of Bulacan, Rizal, Cavite, Laguna, Quezon City, Marikina City, Pasig City, Makati City, Taguig City, and Muntinlupa City could be damaged if the West Valley Fault moves. Not only can The Big One happen in Metro Manila or Luzon, but it can also happen in other parts of the Philippines because of active faults and trenches in the Philippines.

Which Statement Best Describes What Occurs To A Molecule Of The Enzyme Trypsin After It Binds To A Molecule Of Protein?, A)\Tafter Binding To A Protei

Which statement BEST describes what occurs to a molecule of the enzyme trypsin AFTER it binds to a molecule of protein? A) After binding to a protein molecule, the trypsin molecule is destroyed and must be replaced. B) The combined trypsin and protein molecule is utilized for energy to power cellular functions. C) After binding to the protein molecule, trypsin is converted to a lipid and used for energy storage. D) The trypsin molecule is not chemically altered by the reaction with protein and may be used again.   Ans: D)The trypsin molecule is not chemically altered by the reaction with protein and may be used again. ▪Trypsin is an enzyme which catalyses the reaction of proteolysis in humans. ▪Proteins binds to active sites of the enzyme and then it cleaves the peptide bonds of proteins. Resulting product is released out. ▪Trypsin is still unaltered and binds to next protein to cleave it. It is reused.
