Assuming that it's at the same angle the whole way, she goes 1.8 meters down in 3.1 meters down the slides, and if we divide 3.1 by 18 we can find how long the slide is for every 0.1 meter down, which is around 0.17. Multiplying that by 42, we get 7.23 (3 repeating) meters of the slide
Hey there!
A fixed distance along a line without any 2nd dimension is a line segment. The reason why it's a line <em>segment</em> instead of a line is that lines go on forever in both directions while a line segment stops at some point on both ends. This is what the problems means when it says "fixed distance".
Hope this helped you out! :-)
Answer:

Step-by-step explanation:
We are given with two equations
first equation is 
second equation is

we find the result of subtracting two equation
subtract the second equation from the first, so
first equation - second equation, multiply second equation by -1 and then add it with first equation


Now add both equations, we get

5 x 6 + 7? Is that what the answer is, I didn't get the question towards the end. :)
