Can anyone me with this math work : ) you so much

All answers are in the steps below.

Step-by-step explanation:

Question 1(a):

An equation to show the relationship between s and t is:

s = t × k

s = tk

Question 1(b):

The complete table is attached below.

Question 1(c):

Since we now know k = 1/2

s = t × 1/2

s = 1/2t

*You can now easily tackle questions 1(d, e & f).

Question 2(a)

92/35 is not equal to 83/23 thus no proportional relationship between the two variables.

Question 2(b):

20/8 = 12.5/5 = 2.5

There is a proportional relationship between the two quantities here and the constant (k) is 2.5

*Question 3 not complete.
