Answer:
+73 yards.
Step-by-step explanation:
Since we have the first two quarters, we can simply work out the yardage for each game and add them together to get the total.
42-9 = 33 (first game)
58-18 = 40 (second game)
Therefore his total yardage was +73.
Answer:
200 pairs of sandals
Step-by-step explanation:
Represent the sandals with x and the running shoes with y.
In a typical month:
![Total = 2500](https://tex.z-dn.net/?f=Total%20%3D%202500)
In April
![Total = 3000](https://tex.z-dn.net/?f=Total%20%3D%203000)
Required
The number of sandals in a typical month
<u>In a typical month:</u>
If 1 sandal costs 2.50, then x costs 2.50x
If 1 running shoe costs 4, then y costs 4y
The total is:
![2.50x + 4y = 2500](https://tex.z-dn.net/?f=2.50x%20%2B%204y%20%3D%202500)
<u>In April:</u>
If 1 sandal costs 2.50, then 2x costs 5x ---- <em>we used 2x because the pairs is doubled </em>
If 1 running shoe costs 4, then y costs 4y
The total is:
![5x + 4y = 3000](https://tex.z-dn.net/?f=5x%20%2B%204y%20%3D%203000)
The equations are:
![5x + 4y = 3000](https://tex.z-dn.net/?f=5x%20%2B%204y%20%3D%203000)
![2.50x + 4y = 2500](https://tex.z-dn.net/?f=2.50x%20%2B%204y%20%3D%202500)
Subtract
![5x - 2.50x + 4y - 4y = 3000 - 2500](https://tex.z-dn.net/?f=5x%20-%202.50x%20%2B%204y%20-%204y%20%3D%203000%20-%202500)
![2.50x = 500](https://tex.z-dn.net/?f=2.50x%20%3D%20500)
![x = \frac{500}{2.50}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B500%7D%7B2.50%7D)
![x = 200](https://tex.z-dn.net/?f=x%20%3D%20200)
Answer:
All Real Numbers
Step-by-step explanation:
The domain is all the x values for a function. As this function is not restricted in any way, the domain is all real numbers. You can put any number in for x and plot it on the graph.
