Answer:

x = 28 (So it takes 28 hours for the temperature to reach 0°C.)

y = -70 (So the temperature when the experiment begins is −70°C.)

Step-by-step explanation:

To find the the x value, you remove the y value or replace it with 0.

0 = 5/2x - 70

Next you move the variable.

70 (2/5) = x           (multiply 70 by 2 to get 140 and divide that by 5)

And now you simplify to get:

28

To find the y value, you remove the x value or replace it with 0.

y =  0 - 70

And now you simplify to get:

-70

x = 28

y = -70

kompoz [17]

Answer:

24 feet

Step-by-step explanation:

First, I used the proportion method to set up the numbers. I used x for the height of the tree.

x/45 = 6/11.25

Notice that the x and the 6 are both the heights of the tree and Dimitri and that they are both on the top of the fractions.

45 and 11.25 are the lengths of the shadows and they are both on the bottom of the fractions.

Next, I did 6 times 45 and got 270. Then I did 270 divided by 11.25 and got 24.

You're welcome!     :)
