What value of y makes the equation true?
3(2y + 3) = 9y - 15
Answers
Answer:
8
Step-by-step explanation:
First, distribute the 3 on the left side of the equation:
6y + 9 = 9y - 15
Next, move the variables to one side of the equation and the constants to the other:
6y - 9y = -15 - 9
Simplifying the left side:
-3y = -24
Finally, solve for y by dividing both sides by -3:
y = 8
Therefore, the value of y that makes the equation true is 8.

Hello!
The answers are:
B. Before practice, there are 648 ounces of sports drink in the cooler.
C. Each plater drinks approximately 24 ounces of sports drink at practice.
E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice.
Why?
We are given the equation:
Let's discard each of the given options in order to find the three correct options.
A. The cooler is meant to be used only by 24 players: False.
If we want to calculate how many players can use the cooler, we need to isolate "x" (rate of change) from the given equation, so, isolating we have:
We have that the cooler can be used by 27 players, so, the first option that states that "The cooler is meant to be used only by 24 players" is false.
B. Before practice, there are 648 ounces of sports drink in the cooler: True.
We have that before the practice when the cooler is not being used by any player (or there is no any player) has 648 ounces (full), we can calculate it making the variable "x" equal to 0, so, calculating we have:
Therefore, we have that the statement "Before practice, there are 648 ounces of sports drink in the cooler." is true.
C. Each plater drinks approximately 24 ounces of sports drink at practice: True.
From the statement, we know that the rate of change is equal to (-24), and it's equal to the number of ounces that each player drinks.
Hence, we have that the statement "Each plater drinks approximately 24 ounces of sports drink at practice." is true.
D. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink: False.
If we want to calculate the number of ounces that 24 players will drink, we need to use the slope value. If we know that each player drinks 24 ounces, so, to calculate how many ounces of sports drink will 24 players drink, we need to use the following equation:
We have that 24 players will drink a total of 576 ounces, so, the statement "If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink." is false.
E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice: True.
From the statement and the equation, we know that the slope (rate of change) is negative, meaning that for each player (x) it will be 24 fewer ounces of sports drink after practice, for example, calculating for 1 and 2 players, we have:
We can see that for each player, it will be 24 fewer ounces of sports drink after practice.
Hence, we have that the statement "For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice." is true.
Therefore, the correct options are:
B. Before practice, there are 648 ounces of sports drink in the cooler.
C. Each plater drinks approximately 24 ounces of sports drink at practice.
E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice.

Answers
From my understanding and your lack of a picture:
The triangle CAT has rotated in 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.
Step-by-step explanation:
From the given figure it is noticed that the coordinates of the vertices of the pre-image are C(-2,1), A(-3,3) and T(1,1). The coordinates of the vertices of the image are C'(1,2), A'(3,3) and T(1,-1).
From these coordinates, we can conclude that the relation between the preimage and image is
If a figure rotated 90 degrees clockwise direction about the origin, then
Therefore triangle CAT is rotated 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

Doira has a company that sells plants. She sells 34 for plants for $9,000 each her first day. The next couple days she sells 34 for $99,999 each. If she keeps selling them for $99,999 each for 100 weeks,how many plants will she have sold? How much money will she have made?
Answers
Answer:
1)23,800 plants.
2)$2,380,068,200
Step-by-step explanation:
1) if Doira sells 34 plants for $99,999 each for 100 weeks, she will have sold a total of 23,800 plants.
2.On the first day, Doira sold 34 plants for $9,000 each, so she made a total of 34 x $9,000 = $306,000.
In the following days, she sold 34 plants for $99,999 each, so her daily earnings were 34 x $99,999 = $3,399,966.
If she continues to sell 34 plants for $99,999 each for 100 weeks, she will sell a total of 34 x 100 x 7 = 23,800 plants.
Her total earnings from selling 34 plants for $99,999 each for 100 weeks will be 23,800 x $99,999 = $2,379,762,200.
Adding her earnings from the first day, her total earnings will be $2,379,762,200 + $306,000 = $2,380,068,200.
Answer: she would sell 340 plants and make $9,999,900
Step-by-step explanation:
34 x 100 =340
99, 999 x 100 = 9,999,900

What is 5/6 of 14 1/2?
PLEASE explain how it is!
please help its last question and i been on it for 15 minutes
Answers
Answer:
5/6 of 14 1/2 is 12.08333333
Step-by-step explanation:
14 1/2 = 14.5
14 = 14
and 1/2 = 0.5
now, you take 14.5 and divide by the denominator of the fraction that you have, which is 6
14.5 ÷ 6 = 2.416666667
and now you take 2.416666667 and multiply that by 5, because you are trying to find 5/6 of this number
2.416666667 × 5 = 12.08333333
So your answer is 12.08333333
You basically just multiply 5/6 and 14 1/2 which is 145/12 and that simplified is 12 1/12

Grade#7
Answers
Answer: 4x+9
Step-by-step explanation: (8x+12)- (4x+3)
Answer: (4x+9)
Step-by-step explanation:
Log of wood = (8x+12)
piece length = (4x+3)
So, (8x+12) - (4x+3)
=> (8x+12) - 4x - 3
=> 8x-4x +12 -3
=> 4x + 9
So, the length of the remaining piece of wood = (4x+9)

Answer:
x ≠ 6
Step-by-step explanation:
Simplify The Equation,
[tex] \frac{(x + 6)}{x {}^{2} - 36} + \frac{1}{x - 6} \\ = \frac{(x + 6)}{ ({x})^{2} -(6)^{2} } + \frac{1}{x - 6} \\ = \frac{(x + 6)}{(x + 6)(x - 6)} + \frac{1}{x - 6} \\ = \frac{(x + 6) + 1(x + 6)}{(x + 6)(x - 6)} \\ = \frac{x + 6 + 1x + 6}{(x +6)(x - 6)} \\ = \frac{2x + 12}{(x + 6)(x - 6)} [/tex]
Factorize The Equation,
[tex] \frac{2x + 12}{(x + 6)(x - 6)} \\ = \frac{2(x + 6)}{(x + 6)(x - 6)} \\ = \frac{2}{x - 6} [/tex]
From the Given function,
x-6 ≠ 0
x ≠ 6
Thus x ≠ 6 is a restriction.
The solution is : x ≠ 6, is a restriction on the variables
(x+6)/x^2-36 + 1/x-6.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
Simplify The Equation,
(x+6)/x^2-36 + 1/x-6
=(x+6)/(x-6) (x+6) + 1/x-6
= (x+6)+(x+6) /(x-6) (x+6)
=(2x+12)/(x-6) (x+6)
Factorize The Equation,
(2x+12)/(x-6) (x+6)
= 2(x+6) /(x-6) (x+6)
=2/ (x-6)
From the Given function,
x-6 ≠ 0
x ≠ 6
Thus x ≠ 6 is a restriction.

Answer:
The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.
If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).
This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.
This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true. However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations

Find the perimeter and area.
a. Rectangle, L=14m and B=9.5m
b. Square, side=14.5cm
c. Rectangle, L=25cm and B=16.8cm
Grade#8
Answers
Therefore, the perimeter and area of the given shapes are:
a. Perimeter = 47m, Area = 133m²
b. Perimeter = 58cm, Area = 210.25cm²
c. Perimeter = 83.6cm, Area = 420cm²
Step by step solved:
a. To find the perimeter of a rectangle with length L=14m and breadth B=9.5m, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(14m + 9.5m) = 2(23.5m) = 47m
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 14m x 9.5m = 133m²
b. To find the perimeter of a square with side length=14.5cm, we use the formula:
Perimeter = 4 x side
Plugging in the value, we get:
Perimeter = 4 x 14.5cm = 58cm
To find the area of the square, we use the formula:
Area = side²
Plugging in the value, we get:
Area = 14.5cm x 14.5cm = 210.25cm²
c. To find the perimeter of a rectangle with length L=25cm and breadth B=16.8cm, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(25cm + 16.8cm) = 2(41.8cm) = 83.6cm
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 25cm x 16.8cm = 420cm²
Answer:
Step-by-step explanation:
rectangle Perimeter = 2(l+b)
So, 2(14+9.5)
=> 46.5m
area = lb
So, 14*9.5
=> 133m^2
Square Perimeter = 14.5*4
= 58cm
Area = 14.5^2
= 210.25m^2
Rectangle #2
2(25+16.8)
=> 83.6 cm
Area = 420m^2
