I thought of a number n I multiplied it by 6. I added 19. I got 29 more than my number. Equation
Answer:
6n + 19 = 29 + n
n = 2
Step-by-step explanation:
your number = n
multiplied by n by 6 (6 * n or 6n)
6n then add 19 (6n +19)
29 more than my number = 29 + n
add it all together:
6n + 19 = 29 + n
when you solve, n = 2

Answer:
The cost of the t-shirt would be $19.20 with a 20% discount and the amount discounted is $4.80
Step-by-step explanation:
24*0.8 = $19.20
Answer:
Step-by-step explanation:
The discount is:
price × discount
We can substitute the discount of 20% for 0.2 and multiply to find the amount of money taken away which gives us the remaining amount or the amount you pay.

Find the solution to the equation algebraically. Check your answer. k - 16 = 4
Answer:
k= 20
Step-by-step explanation:
You start with this equation:
k-16=4
Add 16 on both sides.
k=4+16
Simply.
k=20
If you want to check your answer, you can just plug 20 into where k is back into the equation:)
Hope this helps!
Hey there!
k - 16 = 4
ADD 16 to BOTH SIDES
k - 16 + 16 = 4 + 16
CANCEL out: -16 + 16 because it give you 1
KEEP: 4 + 16 because it give you the x-value
NEW EQUATION:
k = 4 + 16
k = 16 + 4
SIMPLIFY IT!
k = 20
Therefore, your answer is: k = 20
Good luck on your assignment & enjoy your day!

Answer:
1. y' = 3x² / 4y²
2. y'' = 3x/8y⁵[(4y³ – 3x³)]
Step-by-step explanation:
From the question given above, the following data were obtained:
3x³ – 4y³ = 4
y' =?
y'' =?
1. Determination of y'
To obtain y', we simply defferentiate the expression ones. This can be obtained as follow:
3x³ – 4y³ = 4
Differentiate
9x² – 12y²dy/dx = 0
Rearrange
12y²dy/dx = 9x²
Divide both side by 12y²
dy/dx = 9x² / 12y²
dy/dx = 3x² / 4y²
y' = 3x² / 4y²
2. Determination of y''
To obtain y'', we simply defferentiate above expression i.e y' = 3x² / 4y². This can be obtained as follow:
3x² / 4y²
Let:
u = 3x²
v = 4y²
Find u' and v'
u' = 6x
v' = 8ydy/dx
Applying quotient rule
y'' = [vu' – uv'] / v²
y'' = [4y²(6x) – 3x²(8ydy/dx)] / (4y²)²
y'' = [24xy² – 24x²ydy/dx] / 16y⁴
Recall:
dy/dx = 3x² / 4y²
y'' = [24xy² – 24x²y (3x² / 4y² )] / 16y⁴
y'' = [24xy² – 18x⁴/y] / 16y⁴
y'' = 1/16y⁴[24xy² – 18x⁴/y]
y'' = 1/16y⁴[(24xy³ – 18x⁴)/y]
y'' = 1/16y⁵[(24xy³ – 18x⁴)]
y'' = 6x/16y⁵[(4y³ – 3x³)]
y'' = 3x/8y⁵[(4y³ – 3x³)]
What is the perimeter of a rectangle which measures 300m long and 78m 60 cm wide?
Answer:
75720cm or 757.2m
Step-by-step explanation:
300m = 30000cm
78m & 60cm=7860cm
perimeter of rectangle = 2(length) + 2(width)
2(30000) + 2(7860) = 75720cm or 757.2m

Given:
The graph of a line.
To find:
The coordinates of y-intercept and its coordinate form.
Solution:
We know that, the y-intercept is the point where the graph crosses the y-axis.
From the given graph it is clear that the graph of line crosses the y-axis at point (0,8).
So, the y-intercept is 8.
Therefore, the missing values for the blanks are y, 0, 8, 8 respectively.

Write x² - 6x + 3 in the form (x-a)²+ b.
Answer:
(x + 3)² - 12
Step-by-step explanation:
x²+6x-3
= x²+ 6x + 9 - 12
= (x + 3)² - 12
The form of x² - 6x + 3 can be written as (x-3)² - 6.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given that;
Equation= x² - 6x + 3
Now,
To write x² - 6x + 3 in the form (x-a)²+ b, we can use the method of completing the square. This involves adding and subtracting a constant term to make the expression a perfect square trinomial. Here are the steps:
Write x² - 6x + 3 as x² - 6x + ___ - ___ + 3, leaving two blanks for the constant term.
To find the constant term, divide the coefficient of x by 2 and square it. In this case, -6/2 = -3 and (-3)² = 9. So we fill in the blanks with 9 and get x² - 6x + 9 - 9 + 3.
Factor the first three terms as a perfect square: (x - 3)² - 9 + 3.
Simplify the last two terms: (x - 3)² - 6.
Compare with the form (x-a)²+ b and identify a and b. In this case, a = 3 and b = -6.
Therefore, by the given equation the answer will be (x-3)² - 6.

Krisa divides a number by 10. Then she divides the same number by 50. Which quotient is greater? How can you tell?
Step-by-step explanation:
the quotient of 10 is bigger than the quotient of 50
The quotient is greater when number is divided by 10.
What is division?The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.
Given,
Krisa divides a number by 10
Let the number be x
x/10 = y
x = 10y ------(1)
Same number is divided by 50
x/50 = z
x = 50z --------(2)
By equation (1) and (2)
10y = 50z
y = (50/10)z
y = 5z
⇒ y > z
Hence, quotient when number divided by 10 is greater.
