I think the 3rd one
sorry if i get this wrong
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.

Answer:
Step-by-step explanation:
Let it be x.
<u>Then we have:</u>
- 50 = 1/3x
- x = 50*3
- x = 150 min = 2.5 hr
Answer: p=1.333333
Step-by-step explanation:
Step 1: Subtract 7p from both sides.
2.5p+8−7p=7p+2−7p
−4.5p+8=2
Step 2: Subtract 8 from both sides.
−4.5p+8−8=2−8
−4.5p=−6
Step 3: Divide both sides by -4.5.
−4.5p
−4.5
=
−6
−4.5
p=1.333333
Answer:
union is all <u>unique(haven't any duplicate elements)</u> elements in all sets.
A={ a,e,i} B={a,b,c}
A ∩ B ={ a,e,i,b,c} (Here a is put just one only)
