Answer:
h = 2.5
Step by step explanation:
We have been given an equation that models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill.
To find value of u we will solve our equation.
Upon using distributive property we will get,
Now let us add 18 to both sides of our equation.
Now let us combine like terms.
Upon dividing both sides of our equation by 10.5 we will get,
Therefore, value of u is 2.5.

Answer:
Length of the line segment RS is, 18 cm.
Step-by-step explanation:
Two points are drawn on a ruler. Point R is located at 8 cm and Point S is located at 26 cm.
So, length of the line segment RS is,
(26 - 8) cm\
= 18 cm
We know that on a ruler if two points A and B are at a cm and b cm respectively, then, length of AB
= AB = cm .
