Fabiano wants to score at least 6 . 5 6.5 points in a major chess tournament. He scores 1 1 point for each game that he wins, an
1 answer:
Answer:
Step-by-step explanation:
Let W represent the number of games Fabiano should win and D represent the number games of Fabiano should draw.
We have been given that Fabiano scores 1 point for each game that he wins, so points scored in W games will be 1W=W.
We are also told that he scores 0.5 points for each game that ends in a draw. So points scored in D games will 0.5D.
As Fabiano wants to score at least 6.5 points in a major chess tournament, so total number of points scored in W games and D games should be greater than or equal to 6.5.
We can represent this information in an inequality as:
Therefore, the inequality represents the number of games Fabiano should win and draw to achieve his goal.

Step-by-step explanation:
A temperature falls from 0 to in
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is
Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:
x° = - 3.5
x° =
Thus per hour; the temperature falls at the rate of
