Based on the calculations, the length of the zoo railroad track which does not need to be replaced is equal to 3543/8 or 442.875.

A fraction can be defined as a numerical quantity which isn't expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

In Mathematics, a fraction comprises two (2) main parts and these include the following:

In order to determine the length of the zoo railroad track which does not need to be replaced, we would add all of the length of the zoo railroad track that need to be replaced and then subtract this value from the total length of the zoo railroad track as follows:

Length of replacement = 62/2 + 83/8 + 63/4

Note: Lowest common denominator (LCM) = 8.

Length of non-replacement = (248 + 83 + 126)/8

Length of non-replacement = 457/8

Length of replacement = 500 - 457/8

Length of replacement = (4000 - 457)/8

Length of replacement = 3543/8 or 442.875.

The equation of the line in slope-intercept form is y = 3x + (-7) .

The equation of a line in slope-intercept form can be written as follows,

y = mx + c                                                       equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is -7 -y = -3x .

To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as

    -7 -y = -3x

⇒ y = 3x + (-7)                                             equation 2

On equating equation 1  and equation 2, we will get

Slope of the line = m = 3

Intercept = c = -7

Hello, and thank you for asking your question on Brainly!

This problem is basically telling is to isolate the variable g. But how are we to do so, when it's being sandwiched inside a variety of numbers and letters? The problem looks harder than it seems. But do not fret!

When you're in a trail in the woods and you get lost, the most logical thing is to do the opposite of where you just went in order to try and reach home. We can use this same analogy for math. We just try and use the opposite operation for every action that the function is being acted on!

Let be the original equation,

[tex]u=\sqrt{Ng+Q^3 }[/tex]

Looks pretty complicated right? We want to isolate the variable g, so let's get rid of this 'roof' over their heads.

To get rid of the square root, we can square both sides by two; this negates the square root, and opens up the right section of the equation.

[tex]u=\sqrt{Ng+Q^3 }[/tex]

[tex]u^2 =(\sqrt{Ng+Q^3 })^2[/tex]

[tex]u^2=Ng+Q^3[/tex]
Now, we have to make sure we get the variable g alone. Let's subtract Q cubed to the other side, we can subtract it over to get rid of it on the right hand side.

[tex]u^2=Ng+Q^3\\-Q^3 ~~~~~ -Q^3[/tex]

[tex]u^2-Q^3=Ng[/tex]
We're almost close! Now, all we have to do to isolate the variable g is to divide the whole equation by N, so the right hand side it cancels out. This is the opposite of N multiplied by g.

[tex]\frac{u^2-Q^3}{N} =g[/tex]

It wasn't so bad now, was it? I hope this helped! g is now isolated and this is the end of the problem.

The value of y in the line segment is 4

RT is the total line segment.

Therefore,

RS = 3y + 3

ST = 2y + 8

RT = 31

Hence,

RT = RS + ST

31 = 3y + 3 + 2y + 8

31 = 3y + 2y + 3 + 8

31 = 5y + 11

In order to form a linear equation that describes the amount of data you can use in terms of the amount of money that you are willing to spend, we just need to shuffle the linear equation in order to get the coefficient if q as 1

First step, we need to move 500 from right hand side to left hand side which would change the sign from + to -.

Mary used 96 pounds of type b coffee this month.

Using algebraic expression and equation, we can solve how much of each type of coffee did Mary used that month.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

Given that that month, Mary made 181 pounds of the blend that is a mixture of two types of coffee, we can express this as:

181 = a + b

where a = pounds of type a coffee that costs $5.35 per pound

b = pounds of type b coffee that costs $4.15 per pound

Also, the total cost of the blend that month is $853.15, which is the sum of the total cost of the two types of coffee. We can express that as:

$853.15 = $5.35(a) + $4.15(b)

Using substitution method to solve the two equations,

181 = a + b   ⇒   a = 181 - b

$853.15 = $5.35(181 - b) + $4.15(b)

853.15 = 968.35 - 5.35b + 4.15b

5.35b - 4.15b = 968.35 - 853.15

1.2b = 115.2

b = 96

a = 181 - b

a = 181 - 96

a = 85

Hence, Mary used 85 pounds of type a coffee and 96 pounds of type b coffee that month.

The slope between the two given points (4,5) as well as (1,8) is -1.

A line's slope is a measure of its steepness & direction.

The slope of a line is defined as a change in y coordinate in relation to a change in x coordinate.

        m = Δy/Δx

        where,m is the slope

Now, as per the stated question;

The slope of a line can be calculated using only two points on a straight line. With the coordinates of two points, we can employ the slope of line formula.

Let the coordinates of those 2 points from where the line is passing is;

P1 = (x₁, y₁)

P2 = (x₂, y₂)

The slope of the  line is estimated as;

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

The values of the coordinates are given as;

(x₁, y₁) = (4,5) and,

(x₂, y₂) = (1,8)

Substitute the given values of coordinates in the formula to get the slope;

m = (8 - 5)/(1 - 4)

m = 3/(-3)

m = -1

Therefore, given the coordinates of such two points, the slope of a line passing through them is found to be -1.

x = 3

Answer:

x = 3

Step-by-step explanation:

We need to find to numbers that sum up to make -6 but their product is +9 :

-3 and -3 will do :

Now we split -6x into -3x and -3x :

x² -3x -3x + 9 = 0  

Factorise the first 2 terms:

x(x-3)

Keeping the terms inside the bracket the same as the 1st one factorise the next 2 terms :

x(x-3)-3(x-3) = 0

Keep 1 bracket and make another bracket out of the terms that are outside the brackets :

(x-3)(x-3) = 0

Using the integer rule :

a × 0 = 0

We know that one of these brackets are equal to zero :

x-3= 0

Add 3 to both sides :

x = 3

The other bracket is the same so our final answer is x = 3
