Read the excerpt from the time traveler's guide to elizabethan england. another familiar disease is malaria, which elizabethans refer to as ague or fever. you might associate this with more tropical countries of the modern world but in marshy areas in sixteenth-century england, such as the lincolnshire and cambridgeshire fens, the norfolk broads, and romney marsh in kent, it kills thousands. no one suspects that it has anything to do with mosquitoes; rather people believe it is the corrupted air arising from the low-lying dank marsh (hence the term mal-aria). as a result, you will have no chance of getting proper treatment for the disease. how does the paragraph expand on the central idea that malaria was a deadly disease in elizabethan england

Supporting details, comparisons to other diseases, countries, and possible treatment.  Central idea, often the main idea, needs factual or specific evidence to support, which is how you expand the idea.

In order to expand a central idea, you must use information that is specific to the main idea.  In this case, it was malaria being a deadly disease.  It is expanded upon by talking about the specific time period and how this affected treatment thereby being spread in the air.  

the best option that supports the idea is the third sentence "It explains Elizabethan misconceptions about the spread of malaria."

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
