Answer:

7/14 and 20/40 are proportional.

Step-by-step explanation:

We're looking for the pairs of ratios where the two ratios are equal.

6/21 and 2/42 are not equal, although 6/21 and 12/42 would be equal.

25/100 and 50/150 are not equal.

18/24 and 6/12 are not equal.  Notice that dividing 18 and 24 by 6 results in 3/8, which does not equal 6/12 or 3/6 or 1/2.

In the last case, notice that 7/14 = 1/2 and 20/40 = 1/2.  This pair of fractions is proportional.  Note that 20/7 times 7 is 20 (the numerator of the 20/40), and that 20/7 times 14 is 40.  The constant of proportionality is thus 20/7.

Illusion [34]
The answer is L = 59 + 2(d). If we plug in our numbers, we will get L = 59 + 2(32). 2*32 is 64, and if you add 59 you get 123 miles.

This isn’t apart of the question, but 59 would be the y-intercept. 2 miles per day (2/1) is the slope.
