Answer:
A. 5
Step-by-step explanation:
The marginal benefit of an article, 
is calculated as:
Where 
is the change in the total benefit of the article, and 
is the change in the units of the article.
If we want to know the marginal benefit of watching the 3rd game, we need to use the information of total benefit of watching 2 games and 3 games.
In this case, the total benefit of watching 2 games is 120 and the total benefit of watching 3 games is 125, so and are equal to:
Then, the marginal benefit of watching the third game is:
3/9
24/54
35/5
35/7
Explanation:
express 1/2 with denominator 10
All you have to do is divide the 10 by two and multiply your result by the numerator.
Therefore: 10/2=5
5x1=5
numerator= 5
denominator=10
Answer:
see explanation
Step-by-step explanation:
(1)
The sum of the 3 angles in a triangle = 180° , thus
a + b + c = 180
(2)
adjacent angles are supplementary, thus
b + d = 180
(3)
From (1) and (2)
b + d = a + b + c ( subtract b from both sides )
d = a + c
