A tie-dye kit with one T-shirt costs $15. Each additional T-shirt costs $4 more. Choose the explicit formula to represent the situation.
A. an = 11 + 4n
B. an = 4 + 15n
C. an = 19 + 4n
D. an = 15 + 4(n + 1)
Answer:
a
Step-by-step explanation:
i just took the test
The explicit formula that represents the situation is [tex]a_{n}[/tex] = 11 + 4n thus option (A) is correct.
What is the pattern?A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.
As per the given,
Cost of a tie-dye kit + 1 T-shirt = $15
Additional T-shirt = $4
This, means,
Cost of a tie-dye kit + $4 = $15
Cost of a tie-dye kit = $11
The total cost with n number of T-shirts will be as,
[tex]a_{n}[/tex] = 11 + 4n
Hence "The explicit formula that represents the situation is [tex]a_{n}[/tex] = 11 + 4n".

10. What is the value of x in the solution to the system of equations?
x – 2y = 7
3x + 2y = 21
+/-
Solve for x in first equation:
x-2y=7
Add “2y” to both sides
x=2y+7
Put this in to second equation:
3(2y+7)+2y=21
Solve for y:
Distribute the 3 into the ()
6y+21+2y=21
Combine the like y terms
8y+21=21
Subtract 21 from both sides
8y=0
Divide by 8 on both sides
y=0
Put this into the first solved equation:
x=2(0)+7
Solve for x:
Multiple 2(0)
x=0+7
Add 0 and 7
x=7
So the value of x is positive 7.
Each player will start with $5.00 in a treasure account. The winner will be the player who collects the most money. Which outcome will change a player's account the least? (HINT! Use absolute value.)
Answer:
Find a decoy (-$1.75)
Step-by-step explanation:
Note: The full and organized question is attached as picture below
Each player had $5.00 then they start game. A player can add money to account depending on his/her game. The minimum change in treasure account is caused by game outcome which has corresponding least numerical value from table. The least numerical value from table is for "Find a decoy" which -$1.75 so this out come will make least change in treasure account.

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound
To determine the number of pounds of tomatoes that she bought, x, Carina wrote and solved the equation as shown
below.
3.40+0.85x=5.27
0.85X= 8.67
X= 10.2 pounds
Where, if anywhere, did Carina make an error?
Answer:
Carina made an error in the beginning.
Step-by-step explanation:
Carina didn't do the inverse operation of adding 3.40. She added it to the 5.27 when she shouldve subtracted it. x=2.2 lbs. Hope this helps!
Anwser ( C )
C: Carina should have divided 8.67 by 0.85.

John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?
Answer:
Instead of moving right 4 times and up 7 times, John moved left 4 times and down 7 times.
Step-by-step explanation:
(x + 4, y + 7) = Right 4, Up 7
NOT
(x - 4, y - 7) = Left 4, Down 7
Answer:
The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.
Step-by-step explanation:
Sample Response:The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.
Please solve the equation x+16=9x and show work please
Answer:
2
Step-by-step explanation:
x+16=9x
x-9x=-16
-8x=-16
x=2
+16=9
x+16=9xx+16=9x
Solve
Subtract
16
1616
from both sides of the equation
+16=9
x+16=9xx+16=9x
+16−16=9−16
Simplify
Subtract the numbers
=9−16
x=9x-16x=9x−16
Subtract
9
9x9x
from both sides of the equation
=9−16
x=9x-16x=9x−16
−9=9−16−9
Simplify
Combine like terms
Combine like terms
−8=−16
Divide both sides of the equation by the same term
−8=−16
-8x=-16−8x=−16
−8−8=−16−8
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers

Answer:
C- $4,822
Step-by-step explanation:
4% of 41300 is 1652
4.5% of 44100 is 1984.5
3% of 39500 is 1185
1185 + 1984.5 + 1652 = 4821
4822 is 1 number away from 4821, which is the closest of all of the choices. Therefore the answer is C- 44,822. If this answer helped you please consider giving it brainliest.

intercepts on the y line
Can you please help me with this question?
Answer:
Reflection over the y-axis and a translation down two units
Step-by-step explanation:
You can see that the corners of the triangle have been vertically reflected because of their orientation and then you have to think about what that would look like and decide what else was done to the object. With this, we can tell that the object moved down 2 units.

A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00. How many pounds of fish and pounds of lobster did the market sell?
Given :
A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00.
To Find :
How many pounds of fish and pounds of lobster did the market sell.
Solution :
Let, pounds of fish sells are x.
So, pounds of lobsters sells are (20.5 - x) .
Total amount of spend = 5x + 8( 20.5 - x)
5x + 8( 20.5 - x) = 131
5x - 8x + 164 = 131
3x = 33
x = 11
Therefore, number of pounds of fish and lobsters are 11 and 9.5 pounds respectively.
Hence, this is the required solution.

Megan cut a string into 4 equal pieces. Each piece is 4 fifths of a foot long. How many feet long was the string before Megan cut it? Enter your answer as a mixed number in the solution box. The string was feet long before Megan cut it.
Answer:
[tex]Total = 3\frac{1}{5}ft[/tex]
Step-by-step explanation:
Given
[tex]Pieces = 4[/tex]
[tex]Size = \frac{4}{5}ft[/tex]
Required
Determine the total size of the string
To do this, we multiply the number of pieces by the length of each piece.
[tex]Total = Pieces * Size[/tex]
[tex]Total = 4 * \frac{4}{5}ft[/tex]
[tex]Total = \frac{4 * 4}{5}ft[/tex]
[tex]Total = \frac{16}{5}ft[/tex]
Convert to mixed number
[tex]Total = 3\frac{1}{5}ft[/tex]
