Answer:
B = j + H
Step-by-step explanation:
Given:
j = - H + B
Solve the equation for B
j = - H + B
Add H to both sides of the equation
j + H = - H + B + H
j + H = B
B = j + H
Answer:
true, they can form a triangle.
Step-by-step explanation:
since, sum of two sides is greater than the third side in any case and the difference between two sides is smaller than the third one in all cases.
12 + 6x + 6x + 6y = 12 + 12x + 6y
Answer:
The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
Step-by-step explanation:
The average speed is given by the following equation:

From 10A.M. to noon.
You traveled at 50mph during 2 hours. So how long you traveled?



You traveled 100 miles.
What was your average speed over the time interval from 9 A.M. to noon
From 9 A.M. to 10 A.M, you did not travel.
From 10 P.M. to noon, 100 miles.
So 100 miles during 3 hours.

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
