Here is a model I have made (I'm not a great artist). There are 42 circles in total, placed in 7 columns. Each column has 6 circles. This model represents 42/7 by splitting 42 into 7 parts, which are the columns, and showing that each column has 6 circles, which is the answer to 42/7.

The model to represent 42/7 is shown in the image attached,

A "model" is a representation or abstraction of a system, concept, process, or phenomenon that helps us understand, predict, or explain how things work or interact.

In this image representation, each number  represents one-seventh of the whole. One can shade in six of them to represent 42/7.  In a more technical context,  precise methods of representing fractions, such as using mathematical notation or diagrams is used.

Ryan's error lies in not utilizing the right units for measurement. He used inadequate milk and wrong flour measurement, influencing the recipe's proportion and result.

Ryan's error lies in not utilizing the right units for measurement. The formula calls for 0.25 quart of drain and 2.5 glasses of flour. Ryan utilized 1/5 quart of drain (which is less than 0.25 quart), and rather than utilizing glasses for flour, he utilized 9/4 mugs (which is identical to 2.25 mugs, not 2.5 glasses).

This bungle of units and wrong measurements might lead to the rolls having the off-base consistency and taste due to the awkwardness of fixings. It's imperative to use the desired units and estimations in formulas to realize the expected result.

The process of isolating the variable is the primary step involved in solving an equation.

Thus, option (B) is correct.

A) Substitution refers to the act of replacing a variable with a known value in an equation, which can be a useful strategy in some cases but is not a fundamental step in solving equations.

B) To solve an equation, it is necessary to perform operations that isolate the variable on one side of the equation and keep the other side free of the variable.

C)To verify if the obtained solution satisfies the original equation, but it is not a step required to solve the equation.

D) It states that if a = b, then b = a.

It is a property that allows us to interchange the positions of two equal expressions in an equation but is not directly related to solving equations.

We want to see the properties used to solve the given equation.

The properties used are:

Let's write step by step and see which property we used on each step.

We start with:

[tex]\frac{4}{3} *(\frac{3}{4} *x) = \frac{4}{3} *\frac{1}{4}[/tex]

Now we use the associative property of the multiplication (says that we can multiply in any order we want) we rewrite this to:

[tex](\frac{4}{3} *\frac{3}{4} )*x = \frac{4}{3} *\frac{1}{4}[/tex]

Now we use the existence of the multiplicative inverse, this says that for a number a, there exist a number b such that:

a*b = 1

And we have that b = 1/a.

Then we apply that to the first factor to get:

[tex](\frac{4}{3} *\frac{3}{4}) *x = \frac{4}{3} *\frac{1}{4} \\\\x = \frac{4}{3} *\frac{1}{4}[/tex]

Again, using the same but with the numerator of the first factor of the right side and the denominator of the second factor of the right side we get:

[tex]x = \frac{4}{4} *\frac{1}{3} = \frac{1}{3}[/tex]

Step-by-step explanation:

since we have -5 and 3, in order to translate f(g) into f(x), we subtract 8 from f(g)

The graph of g(x) is the same as the graph of f(x) translated up 8 units. Therefore, option B is the correct answer.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Given that, f(x)= 6x-5 and g(x)= 6x+3.

When the shape is moved up by k units, then replace y with y + k.

Here, g(x)=6x-5+8

g(x)= 6x+3

The graph of g(x) is the same as the graph of f(x) translated up 8 units. Therefore, option B is the correct answer.

Hi there!

F(n) = F(n - 1) + 2 (Meaning, the next "n" is 2 added to the previous)

We can count up to f(4) using this logic:

f(2) = F(2 - 1) + 2 = F(1) + 2 = 6 + 2 = 8

f(3) = F(2) + 2 = 8 + 2 = 10

The solution is, the slope of the line below is 1/2.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

from the given graph, we get,

the line is passing through the points (-2, -3 ) and, (2, -1 )

now , we know that,

We can find the slope of a line given two points by using the following:

m = ( y2-y1)/(x2-x1)

so, substituting the values of the coordinates of the points,

we get,

m = -1 + 3 / 2 + 2

   = 2 / 4

   = 1/2

Hence, The solution is, the slope of the line below is 1/2.

Using polynomial division, it is found that the expression that represents the amount of candy sold each year per type at Cassandra's Candy Corner is:

[tex]2x^2 - 5x + 52[/tex]

The amount of candy sold per type is given by the following division:

[tex]\frac{C(x)}{T(x)} = \frac{4x^3 + 10x^2 + 54x + 520}{2x + 10}[/tex]

The denominator can be written as:

[tex]2x + 10 = 2(x + 5)[/tex]

At the numerator, to see if we can simplify, we verify if x = -5 is a factor:

[tex]C(-5) = 4(-5)^3 + 10(-5)^2 + 54(-5) + 520 = 0[/tex]

Since C(-5) = 0, it is a factor of the numerator, and thus, since the numerator is of the 3rd degree, it can be written as a 3 - 1 = 2nd degree polynomial multiplying x + 5:

[tex](ax^2 + bx + c)(x + 5) = 4x^3 + 10x^2 + 54x + 520[/tex]

[tex]ax^3 + (5a + b)x^2 + (5b + c)x + 5c = 4x^3 + 10x^2 + 54x + 520[/tex]

Equaling both sides:

[tex]a = 4[/tex]

[tex]b = 10 - 5a = -10[/tex]

[tex]5c = 520 \rightarrow c = 104[/tex]

Thus:

[tex]C(x) = (4x^2 - 10x + 104)(x + 5)[/tex]

And:

[tex]\frac{C(x)}{T(x)} = \frac{(4x^2 - 10x + 104)(x + 5)}{2(x + 5)} = 2x^2 - 5x + 52[/tex]

Thus, the expression is:

[tex]2x^2 - 5x + 52[/tex]
