3roads, a, b, and c. b is three times longer than a. c is twice as long and b. draw the roads. what fraction of the total length of the roads is the length of a? if road b is 7 miles longer than road a, what is the length of road c?

The fraction of the total length of the road is 1/10 the to the length of a and the value of c = 21 units.

Data;

Let's try to find the total length of the road.

Let's solve in terms of a

The length of the road in terms of a is 10a

The fraction of the total road is the length of a

1/10 is the fraction of a to the total length of the road.

b)

If b = 7 + a, c = ?

but c = 6a

substitute the value of a

From the calculations above, the fraction of the total length of the road is 1/10 the to the length of a and the value of c = 21 units.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

answer: (3,11) is your answer.
