How to find the greatest number of cards that she can place in a row?The number of cards for each family is given as follows:
April's family: 154.Groom's family: 140.We want to find a way to distribute them having the same number of cards in each row, hence this is possible finding the greatest common factor (GCF) of the numbers of 154 and 140.
The GCF is found factoring both numbers 154 and 140 simultaneously by prime factors, as follows:
154 - 140|2 (both 154 and 140 are divisible by 2).
77 - 70|7 (both 77 and 70 are divisible by 11).

It would cost him $ 5 to cover a distance of 2 miles.
Amount charged by the taxi driver which is mandatory to be paid is $ 2.50
Additional amount charged by the driver is $1.25
Since Ian is driving 2 miles thus we can write it as follows :
2.50 + (1.25 × 2) = 2.50 + 2.5
= $5
The additional charges are basically the amount which is charged by the driver to cover a particular distance and thus this distance changes as the distance changes.

can someone explain functions to me please I don't get it.
Functions are special relaionships that connect an element of one set of numbers, with one element in another set of numbers.
The most comon way to represent functions is connecting elements of a set of Real numbers called the "Domain", to another number in a set called the Range (and whose elements are identified with the letter "y")
Using math operations one can relate x values with y values via an equation of the type:
y = 2 x - 5
where you have a mathematical form of that relationship, that allows you to know given the value of one member (x) of the Domain what number is associated with it in the Range.
For example, try the number x = 0
and see which y number connects with it:
y = 2 (0) - 5 = 0 - 5 = -5
Then you say that the number 0 in the Domain connects with the number -5 in the Range.
This relationship can also be given with coordinate pairs of the form:
(x, y) mentioning in the first position (where the x is), the number in the Domain that connects to the "y" number of the Range). The y goes in the second place. so for example in the relationship we found above, x = 0 connects with y=-5, you would have a shortcut way to write it as the pair: (0, -5) that tells you which x connects with which y.
The functions can also be given in graph form by plotting the relationship between members of the Domain and the Range on the plane. Graphing a point in the plane location that corresponds to the connected x and y values (like you do in the game "battlefield" when you locate ships on the board.
I know this is very general, but hopefully you got the idea ofa function as a special relationship between numbers, and that they can be expressed in different fashions.

2. The admission fee at a small fair is $2.50 for children and $4.00 for adults. On a certain day, 2400 people enter the fair and $7140 is collected. How many children and how many adults attended?
Given:
a.) The admission fee at a small fair is $2.50 for children and $4.00 for adults.
b.) On a certain day, 2400 people enter the fair and $7140 is collected.
Let,
x = total number of children
y = total number of adults
Let's generate two equations based on the given scenario:
EQUATION 1: Total number of children and adults entered the fair.
[tex]\text{ x + y = }2400[/tex]EQUATION 2: Total money collected from the admission.
[tex]\text{ 2.5x + 4y = }$7140$[/tex]We will be using the substitution method. We get,
[tex]\text{ x + y = }2400[/tex][tex]\text{ y = }2400\text{ - x}[/tex]Substitute to Equation 2:
[tex]\text{ 2.5x + 4y = }$7140$[/tex][tex]\text{ 2.5x + 4(}2400\text{ - x) = }$7140$[/tex][tex]\text{ 2.5x + 9600 - 4x = }$7140$[/tex][tex]\text{ 2.5x - 4x = }$7140$\text{ - 9600 }[/tex][tex]\text{ -1.5x }=\text{ }-2,460[/tex][tex]\text{ }\frac{\text{-1.5x}}{-1.5}\text{ }=\text{ }\frac{-2,460}{-1.5}[/tex][tex]\text{ x }=\text{ }1,640\text{ children}[/tex]Therefore, 1,640 children went to the fair.
For the adults,
x + y = 2400
1,640 + y = 2400
y = 2400 - 1,640
y = 760 adults
In summary: 1,640 children and 760 adults went to the fair.

Repeating decimal values are created by fraction that do not divide evenly. when converting a repeating decimal to a fraction we can ignore the units in the start as the units remain unchanged ,which allows us to convert our decimal values and then the units back in afterward.
so ,
To convert the 3.83 to a fraction , we ignore the units as they will remain units.
we then set up one equation of our unknown x being equal to 0.83333......and another that is 100 times greater , 100x = 83.33333....
by subtracting these two equation from each other we can then divide by the coefficient of x to create our fraction .
10x=83.3333...
x= 0.83333...
99x = 82.5
we now divide both sides by 99 to isolate x:
99x=82.5
99x/99=82.5/99
x= 82.5/99
x = 82.5 x10/99x10
x = 825/990

What is meant by percent error?The difference between the estimated value and the actual value in relation to the actual value is known as the percent error. To calculate the percent error, the relative error is multiplied by 100.
Percent error calculates the difference between an estimate and a correct value and expresses it as a percentage. Analysts can use this statistic to determine how big the error is in relation to the actual value. It is also referred to as % error and percentage error.
%error = (calculated value - experimental value) / calculated × 100%

Consecutive terms in the α sequence have a common difference of

so they are given recursively by
[tex]\begin{cases} \alpha_1 = 10 \\ \alpha_n = \alpha_{n-1} - 2 & \text{for } n\ge2 \end{cases}[/tex]
By substitution, we have
[tex]\alpha_n = \alpha_{n-1} - 2 \\\\ \alpha_n = \alpha_{n-2} - 2\cdot2 \\\\ \alpha_n = \alpha_{n-3} - 3\cdot2 \\\\ \vdots \\\\ \alpha_n = \alpha_{n-(n-1)} - (n-1)\cdot 2 = \alpha_1 - 2(n-1) = 12-2n[/tex]
Consecutive terms in the β sequence have a common ratio of

so the recurrence for these terms is
[tex]\begin{cases} \beta_1 = 9 \\\\ \beta_n = \frac23 \beta_{n-1} & \text{for } n\ge2 \end{cases}[/tex]
We can solve for [tex]\beta_n[/tex] similarly:

The γ sequence has [tex]n[/tex]-th term
[tex]\gamma_n = \alpha_n \beta_n = (12-2n) \dfrac{2^{n-1}}{3^{n-3}} = (108-18n) \left(\dfrac23\right)^{n-1}[/tex]
and we want to compute
[tex]\displaystyle \sum_{n=1}^\infty \gamma_n = 108 \sum_{n=1}^\infty \left(\frac23\right)^{n-1} - 18 \sum_{n=1}^\infty n \left(\frac23\right)^{n-1}[/tex]
Recall the sum of an infinite geometric series with common ratio [tex]|r|<1[/tex] converges to
[tex]\displaystyle \sum_{n=1}^\infty r^{n-1} = \frac1{1-r}[/tex]
so that
[tex]\displaystyle \sum_{n=1}^\infty \left(\frac23\right)^{n-1} = \frac1{1-\frac23} = 3[/tex]
For the remaining sum, we can use the method shown in question [24494877] to compute
[tex]\displaystyle \sum_{n=1}^\infty nr^{n-1} = \frac1{(1-r)^2}[/tex]
which gives
[tex]\displaystyle \sum_{n=1}^\infty n \left(\frac23\right)^{n-1} = \frac1{\left(1-\frac23\right)^2} = 9[/tex]

-Determine the equation of the line that passes through the point (9, -42)and is parallel to the line y = -5x + 1.Enter your answer in slope-intercept form.Pls see picture
Two parallel lines have the same slope. Given the equation of one of the lines, you can determine the slope of the other line:
[tex]y=-5x+1[/tex]The slope of the line is the coefficient of the x-term, in this case, that coefficient is -5. Then the slope of both parallel lines is m= -5.
The line you have to find must cross through the point (9,-42). Using the point-slope form you can determine the equation of the parallel line:
[tex]y-y_1=m(x-x_1)[/tex]Where
m is the slope of the line
(x₁,y₁) are the coordinates of one point of the line:
[tex]\begin{gathered} y-(-42)=-5(x-9) \\ y+42=-5(x-9) \end{gathered}[/tex]To write the equation in slope-intercept form, the first step is to distribute the multiplication on the parentheses term:
[tex]\begin{gathered} y+42=(-5)\cdot x+(-5)\cdot(-9) \\ y+42=-5x+45 \end{gathered}[/tex]Subtract 42 to both sides of the expression to pass the term to the right side of the equal sign:
[tex]\begin{gathered} y+42-42=-5x+45-42 \\ y=-5x+3 \end{gathered}[/tex]The equation of the line is y= -5x + 3

2x-6y=-3
Determine if the given ordered pair. (3, 7/2)
satisfies the given equation.
O YES O No
Answer:
No, it doesn't satisfy.
Step-by-step explanation:
2x - 6y = -3
let us post the ordered pair in the equation and solve it
2(3) - 6(7/2) = -3
6 - 21 = -3
-15 = -3 ...... which isn't equal
so we conclude that the given ordered pair doesn't satisfy the equation.
