The option D.15 + 40 = 5(3 + 8); demonstrates the distributive property.
What is the meant by the term distributive property?To "distribute" something means to divide it or give a fraction or portion of it.The distributive property corresponds to the distributive law of multiplication over basic arithmetic operations such as addition and subtraction.This property states that multiplying a sum of two or even more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.In other words, the distributive property requires an expression of the form: A (B + C) can be written as AB + BC.This property also applies to subtraction: A (B - C) can be written as AB - BC.This indicates that other two operands share operand A.From the given options;
Consider option D; 15 + 40 = 5(3 + 8).
It is the case of distributive addition.
where
5(3 + 8) = 5×3 + 5×8
5(3 + 8) = 15 + 40
Thus, the option D is the correct representation of the distributive law.

Given that, a company rents out 14 food booths and 21 game booths at the county fair. The fee for a food booth is $175 plus $9 per day. The fee for a game booth is $50 plus $8 per day.
What is an expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Given, the fair lasts for d days, and all the booths are rented for the entire time.
So, Food Booth Fee can be calculated as follows:
14(175+9d)
=2,450+126d
Game Booth Fee can be calculated as follows:
=21(50+8d)
=1050+168d
So, the total Food and Game Booth Fees:
=2,450+126d+1050+168d

Write an equation of each line in point-slope form.
(-4,-3) and (2,7
The equation of the line in point-slope form, which passes through the pair of points located at (-4 , -3) and (2 , 7), is y + 3 = 5/3(x + 4).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (-4 , -3) and (2 , 7).
m = (y2 - y1)/(x2 - x1)
m = (7 - -3)/(2 - -4)
m = 10/6
m = 5/3
Using the point slope form, plug in the values of the slope and Point A to set up the equation.
(y - y1) = m(x - x1)
where m = 5/3 and (x1 , y1) = (-4 , -3)
(y - -3) = 5/3(x - -4)
y + 3 = 5/3(x + 4)

The recipe of flour and sugar can be given as an example where we will get the ratio as 4 : 1.
The example is with flour and sugar
Let
x = the number of cups of flour

We know that:
Ratio means the comparison between the two values.
Ratio = x / y
Now, we can let
x = 1 / 2 cups of flour
y = 1 / 8 cups of sugar
Ratio will be

What is the constant of proportion?
A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.
Solving for the value of y
let k be the constant of proportion
When a quantity varies directly with others, then we have a relation, y = kx —-- 1
Now, find k for given x = 3 / 4 and y = 5 / 3, we need to put these values in equation 1, i.e.
5 / 3 = k(3 / 4)
k = (5 × 4) / 9
k = 20 / 9
Further calculate x for given y = ½ and constant of proportion = 20/9i.e.
½ = (20 / 9)x
x = 9 / 40
Hence, the required value of x is 9 / 40.

Write an explicit formula for each geometric sequence. 25,5,1, 1/5, . . .
The explicit formula is [tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]
For the Geometric sequence, the explicit formula for the nth term is
[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]
Where,
a = first number of the series
r = common ratio
n = number of series
[tex]a_{1}[/tex] = a
[tex]a_{2}[/tex] = ar
[tex]a_{3}[/tex] = a [tex]r^{2}[/tex]

A group is going to a state fair. If childrens tickets are $7.50 per child and adult tickets are $12 per adult, how many of each can go to the fair for $200? Write a linear equality, graph it, and show several solutions on graph. !! Help
Let c = children tickets
Let c = children tickets Let a = adult tickets
Let c = children tickets Let a = adult tickets Let c to be in place of x
Let c = children tickets Let a = adult tickets Let c to be in place of xLet a to be in place of y
Answer:
7.50c+12a<or=200 (you would have a inequality since that is the maximum number you could pay and no other information is given)
the graph is above and the inequality in slop intercept format is y= -5/8x+ 16 2/3
Solutions for c: 0 <or= c <or= 26* *(since that is the maximum whole number you can have for $200)
Solutions for a: 0 <or= a <or= 16* *(since that is the maximum whole number you can have for $200)
Note: In order for find other solutions your cordatnate has to be a whole number (that is positive or zero) within the red area shaded. However there are many examples given for answer purposes.
Step-by-step explanation:
$7.50 is the price of each children tickets and $12 is the price of each adult tickets and when combined equal to $200 so you can multiply the variables to get 7.5c+12a <or= 200.
To graph the inequality there's two ways;
Way 1: Change from standerd form to slope intercept form
Place 7.50c on the right side by subtracting 7.50c on each side of the inequality (the point is to islolate a); 7.50c - 7.50c + 12y < or = 200 - 7.50c. The 7.50c on the left side cancel each other out so we'll get 12a < or =200 - 7.50c Isolate a by dividing both sides by 12; 12a/12= (200 - 7.50c)/12 that equals to a < or = -5/8c + 16 2/3 Find an appropriate scale and graph you can use the a-interpect and c-intercpt to make a line since this is less than or equal to you shade the region below the lineWay 2: Isolate your variables to get your x and y intercept
To find the a-interpect you make c equal to 0 so it would be 12a = 200Divide 12 on both sides; 12a/12 =200/12. The a-interpect is 16 2/3 To find the c-intercpt you make a equal to 0 so it would be 7.50c = 200. Graph the point on your graph Divide 7.50c on both sides; 7.50c/7.50 =200/7.50.
