X = 2 for the first one by cross multiplying......sorry about not having time for the other 2
Answer:
0 =n
Step-by-step explanation:
2 − 10n = 2 + 4n
Add 10n to each side
2 − 10n+10n = 2 + 4n+ 10n
2 = 2 + 16n
Subtract 2 from each side
2-2 = 2+16n-2
0 = 16n
Divide each side by 16
0/16 = 16n/16
0 =n

-0
Step-by-step explanation:
The equations that can be used are 10T + 5S = 190 and T + S = 30.
<h3><u>Equations</u></h3>
Given that the girls tennis team was interested in raising funds for an upcoming trip, and the team sold tumblers for $10 and sun hats for $5, and when the sales were over, the team had earned $190 and sold 30 total products, which included a mix of tumblers and hats, to determine which equations can be used to represent the situation, the following calculations must be made:
- T + S =190
- -It cannot be used because it has any relationship with the price of the products.
- 10T + 5S = 30
- -It cannot be used because it only considers the quantity variable.
- T + S = 30
- -It can be used as it shows the amount of products sold.
- 10T + 5S = 190
- -It can be used because it relates the total price to the quantity of each product.
- T + S = 15
- -It cannot be used because it only considers the price variable.
- 5T + 10S = 190
- -It cannot be used because it erroneously relates the price of each product.
Therefore, the equations that can be used are 10T + 5S = 190 and T + S = 30.

Just do 23 minus 6 and that should be the answer because the y-ccordinate is in the same place
