Investigation 1.6 Drawing Pictures to Visualize Problems Solve each of the following problems by first drawing a picture or figure. How did the figure help
you solve the problem?
(a) Four cities, conveniently named A, B, C, and D, lie along a very straight road,
not necessarily in that order. B is between Cand D, and D is between B and A. The
distance from B to C equals the distance from A to D, which is twice the distance
from B to D. The distance from A to C is 250 mi. What is the distance from A to B?
Justify your answer.
(b) In her back yard, Carmen wants to build a swimming pool that is 12 ft by 40 ft.
She also plans to build a deck that is 6-ft wide surrounding the pool. What is the
area of the deck?

the answer is (-4,-4)

hope this ! : d

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.

im not sure of the names, but the answer is 48
