Answer:
12<u> = </u>7<u> + </u>2<u> + </u>3
Step-by-step explanation:
Given:
Number of games played last week = 12
Number of games played on Monday this week = 7
Number of games played on Wednesday this week = 2
Also given:
James and Amy play 3 more games.
So Number of games played more = 3
We need to fill in the blanks 12 __ 7__2__3 with signs '+', '-','='.
Solution:
It is given that they have played the same number of games as last week.
So we can say that;
Number of games played last week is equal to Number of games played on Monday this week plus Number of games played on Wednesday this week plus Number of games played more.

Let be 0 the sea level.
Since the heron is perched in a tree 50 feet above sea level and directly below the heron the pelican is flying 17 feet above sea level, you can find the difference in height between the pelican and the heron by subtracting 50 feet from 17 feet.
Then, you get that this is:
Now, according the the information given in the exercise, you know that the trough is swimming directly below them and its height is 23 feet below sea level. If you represent this with an integer, this is:
Therefore you can find the difference in height between the pelican and the trout through the following subtraction:
And the distance between them is 40 feet too.
