Violet was given a box of assorted chocolates for her birthday. Each night, Violet treated herself to some chocolates. Violet ate 4 chocolates each night and there were originally 24 chocolates in the box. Write an equation for C,C, in terms of t,t, representing the number of chocolates remaining in the box tt days after Violet's birthday.
Answer:
C = 24 - 4t
Step-by-step explanation:
Total chocolate = 24 chocolate
Quantity eaten each night = 4
Let
C = number of chocolate remaining
t = number of days after violet birthday
Number of chocolate remaining = original number of chocolate - 4(number of days after violet birthday)
C = 24 - 4t
For instance, if t = 2
That is, 2 days after violet birthday
C = 24 - 4t
= 24 - 4(2)
= 24 - 8
= 16
Answer: C = 24 - 4t

the length of a rectangle is twice its width. the perimeter of the rectangle is 42cm. what is the length and width for the rectangle?
Answer:
length = 14cm width = 7cm
Step-by-step explanation:
length = 2x w (width)
if length = 2x width then
length must equal 4/6 and width must equal 2/6 because length is 2 times width.
42 divded by 6 = 7.
length gets four lots of 7.
length of both sides= 28cm
width gets 2 lots of 7.
width of both sides= 14cm
there are two sides for length and two sides for width.
Length x 2= 28cm
Length must equal 14cm.
Width x 2 = 14cm
Width must equal 7cm.
lets just prove this is true:
7+7=14.
14+ (14+14) =
14+ 28= 42cm.
this works.
the length is 14cm and the width is 7cm.
Answer:
Length = 14 cm
width = 7 cm
Step-by-step explanation:
given:
rectangle
where L = 2W
W = W
Perimeter = 42 cm
find: Length of L
solution:
Perimeter or a rectangle = 2L + 2W
plugin the given values into the formula:
42 = 2(2W) + 2W
42 = 4W +2W
42 = 6W
W = 42/6
W = 7 cm (width of Rectangle)
solve L by using substituting W=7 in L = 2W
L = 2W
L = 2 (7)
L = 14 cm
therefore, the Length = 14 cm
width = 7 cm
What is the solution of this equation? 7y -4 = 9y +13 -4y
Answer:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8[tex]\frac{1}{2}[/tex] or 8.5

What is the slope of the line ?
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Answer:
To find the slope, you will have to divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those h same 2 points .

20 (20 minus x) = 300 What is the value of x?
Answer:
5
Step-by-step explanation:
20 ( 20 - x ) = 300
By transposing,
20 - x = 300 / 20
20 - x = 15
-x = 15 - 20
-x = -5
- and - get cancelled
so, x = 5

Step-by-step explanation:
In order to find the midpoint of LQ, we need to find how long it is.
We can do this by finding the distance between L (-4) and Q (8).
From -4 to 0, it's 4.
From 0 to 8, it's 8.
So the total distance is [tex]8+4=12[/tex].
The midpoint of 12 units will be 6 units past L. We know that L is -4 so let's add 6 to it.
[tex]-4 + 6 = 2[/tex]
N is located at 2, so N is the midpoint of LQ.

How do you solve for x and y in this matrix equation?
Answer:
Hi!
I might be able to help you!
The Matrix Solution
It means that we can find the values of x, y and z (the X matrix) by multiplying the inverse of the A matrix by the B matrix.
The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method. Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.
I apologize if this didn't help you, but God bless you and your family!
