What is the author's most likely purpose in presenting Dr. Richardson's research?
Read the excerpt from Chapter 2 of Wheels of Change.
Dr. Benjamin Ward Richardson of Great Britain, a big fan
of the wheel, nevertheless summarized its pitfalls in his
1895 article "What To Avoid in Cycling." Among those
pitfalls were several dangers that resulted from "teaching
the practice to subjects who are too young." Richardson
believed serious riding should not be done by males or
females until the skeleton was completely matured,
which he said happened around age 21.
o to persuade young readers to avoid riding bicycles
until they are older
O to entertain readers with a story about a doctor who
was against cycling
to inform readers about one reason why cycling was
controversial in the 1800s
to emphasize that the advantages of cycling are not
worth the risks

To inform readers about one reason why cycling was controversial in the 1800s

Explanation:

The reason why the author mentions Dr. Richardson's research is to inform the readers about one reason why cycling was controversial in the 1800s.

Wheels of Change is a book written by Sue Macy about how important cycling was in the emancipation of women in late-nineteenth-century America. The purpose of the book is mostly to inform - not to persuade or entertain. Dr. Richardson is a prominent figure from that time, and Macy tells us about his opinion on this matter.  

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
