Answer:

29 inches

Step-by-step explanation:

For the following I just used trial and error and experimented with the possibilities:

29 inches - This is the only one that does not work.

30 inches - We can use 5 of the 6 inch trains, so this is possible.

31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.

32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.

33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

The points (10,14) and (35,49) form a proportional relationship. Find the slope of the line through the points. Then use t

The slope is 7/5 and the equation of the line is 5y - 7x = 0 if the points (10,14) and (35,49) form a proportional relationship.

<h3>What is the slope?</h3>

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

$\rm m =\dfrac{y_2-y_1}{x_2-x_1}$

From the above formula, we can find the slope of the line:

m = (49-14)/(35-10)

m = 35/25

m = 7/5

The equation will be:

y = 7x/5 + c

here c is the y-intercept

Plug (10, 14) in the equation to find the value of c

14 = 7(10)/5 + c

c = 0

y = 7x/5 or

5y - 7x = 0

Thus, the slope is 7/5 and the equation of the line is 5y - 7x = 0 if the points (10,14) and (35,49) form a proportional relationship.
