What is a common factor?
A whole number that is a factor of two or more numbers is referred to as a common factor.
The largest factor that will split into two or more integers is known as the highest common factor (HCF).
The smallest multiple shared by two or more numbers is known as the lowest common multiple (LCM).
The LCM and HCF
when a fraction is added or subtracted.
can be discovered by listing multiple factors. It is more effective to express greater values of a number as the product of prime factors. The Venn diagram is another option.
In finding common factors, the HCF, and LCM need knowledge of how to identify factors, build factor trees, and express integers as the product of their prime factors.
How to locate common factors?
A whole number that is a factor of two or more numbers is referred to as a common factor. Example: The common factors of 30 and 20 are 2, 5, and 10.
A factor that all whole integers share is 1, or 1.
To identify commonalities:
List each number's factors.
To identify the numbers that are the same (or frequent) in both lists, compare the factors.

Using linear functions, it is found that:
a) The expression to convert from Fahrenheit to Celsius is: y = 5x/9 - 160/9.
b) The inverse expression is: y = 9x/5 + 32.
What is a linear function?The slope-intercept representation of a linear function is given as follows:
y = mx + b
The coefficients of the function are described as follows:
m is the slope of the function, representing the rate of change of the output y in relation of the input x of the function.b is the y-intercept of the function, representing the numeric value of the function when the input x is of 0.For the conversion of Fahrenheit to Celsius, we have two points, as follows:
(32,0), (68, 20).
When the input increases by 36, the output increases by 20, hence the slope is calculated as follows:
m = 20/36 = 5/9
Hence:
y = 5/9x + b.
When x = 32, y = 0, hence the intercept b is calculated as follows:
0 = 5/9(32) + b
b = -5 x 32/9
b = -160/9
Hence the equation is:
y = 5/9x - 160/9.
To find the inverse expression, we exchange x and y and then isolate y, as follows:
x = 5/9y - 160/9.
5/9y = x + 160/9
5y = 9x + 160
y = 9x/5 + 32.

In baseball, Ken gets on base 60% of the time he bats. If Ken bats 5 times, how many times did he get on base?
Assuming Ken gets the same percentage as usuall in these 5 times, we can calculated how many times he did get on base by calculating 60% of 5.
To do this we transform 60% into decimal my dropping the percentage sign and dividing it by 100 and then we multiply the decimal by 5:
[tex]\frac{60}{100}\cdot5=0.6\cdot5=3[/tex]So, Ken got on base 3 times.

each of one senior citizen ticket and one child ticket?
Each senior citizen ticket costs $7.
One child's ticket costs $14.
Describe algebra.
Algebra is one of the numerous subfields of mathematics. The study of mathematical symbols and the rules for employing them in formulas is commonly referred to as algebra, which runs across almost all of mathematics.
S represents the senior citizen ticket cost.
C is the child's ticket cost.
Price is expressed as USD per ticket.
8S + 15C = 266
8S + 8C = 168
Subtract both equations now to get rid of S
8S + 15C = 266
8S + 8C = 168
———————————-
7C = 98
C = 98/7
C = $14
Changing the value of C in the first
8S + 15(14) = 266
8S + 210 = 266
8S = 266 - 210
8S = 56
S = 56 / 8
S = $7
Hence, $7 is the price for senior citizen

Given the function
[tex]\begin{gathered} f(x)=\frac{1}{7}x^2 \\ x\ge0 \end{gathered}[/tex]To find the inverse, we must recall that the domain of the function becomes the range of the inverse function and vice-versa.
We are already given the domain of f, all the real numbers equal or greater than zero.
The domain of the function is exactly the same because x squared is always positive or zero, thus the domain and range of the inverse should be x≥0.
Once we find the inverse function, we'll use this concept.
Step 1: Substitute f(x) for y:
[tex]y=\frac{1}{7}x^2[/tex]Step 2: Swap the variables:
[tex]x=\frac{1}{7}y^2[/tex]Step 3: Solve for y:
[tex]y=\pm\sqrt[]{7x}[/tex]But as said above, the range of this function cannot include the negative numbers, thus the inverse function is:

Solution A is 12% alcohol and Solution B is 20% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 176 milliliters of pure alcohol?
Using the concept of volume, 700 milliliters of Solution B was used.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
When dealing with unknowns, the first step is to represent the unknowns using variables, draw up equations based on the available data, and then solve those equations to account for the unknowns.
Volumes of solutions A and B are here which is unknown.
Put these factors in place for us
Let x = the amount of solution A that was mixed in milliliters.
Let y= the amount of solution B that was mixed in milliliters.
The amount of volume utilized for A is 400 ml less than the amount used
for B.
This can be expressed mathematically as y - x = 400.
Or,
- x + y = 400 [1]
The ratios of alcohol in A and B are provided to us.
A contains 12% alcohol, hence its real alcohol content is 12% of x ml.
= 0.12x (12% = 12/100 = 0.12)
Similar to A, B has an alcohol content of 0.20x.
If x of A and y of B are combined, the total alcohol by volume is 0.12x + 0.20y.
and it is said that this amount is 176 ml.
Our second equation is therefore set up as 0.12x + 0.20y = 176 [2].
We create an equation containing only the other term by using both equations and removing either the x or y terms.
We should remove the x term from both equations to create a single equation that just contains the y term because the question only asks us to compute the volume of Solution B that was used.
Review the equations now:
- x + y = 400 [1]
0.12x + 0.20y = 176 [2]
x's coefficients should all be the same:
Increase [1] by 0.12
=> -0.12x + 0.12y =
= 0.12 x 400
=> 0.12x + 0.12y = 48 [3]
By adding [2] and [3], the x word is removed.
0.12x + 0.20y = 176+( -0.12x) + 0.12y = 48
0x + 0.32 y = 224
=> 0,32y = 224
Subtract 0.32 from both sides to get[tex]\frac{0.32y}{0.32}[/tex] = [tex]\frac{224}{0.32}[/tex]
==> y = 700
Therefore, 700 cc of Solution B was utilized.

find an equation parallel to y=-8 and passing through (-6, -7)
Given:
an equation is given as y = -8.
Find:
we have to find an equation parallel to the given equation and passing through (-6, -7).
Explanation:
Compare the given equation with y = mx + b,
we find that slope ,m = 0 ,
the equation of the line passing through (-6,-7) is
y - (-7) = m( x - (-6))
y + 7 = 0(x + 6)
y + 7 = 0
y = -7
Therefore, y = -7 is an equation which is parallel to y = -8 and passing through ( -6, -7).
The graph of both y = -8 and its parallel equation y = -7 which passes through (-6, -7) is given as below
Red line represents the equation y = -8
and blue line represents the equation y = -7 passes through the point (-6,-7).
Therefore, the equation of the line parallel to y = -8 and passing through (-6,-7) is y = -7.

How to solve the equation in slope intercept form?We are told that the average price in the year 2004 was $294000
We are told that y is the average price in a home in the year x, where x = 0 represents the year 2004. Thus, this means that the y-intercept is $294000.
Since the line must pass through the points (0, 294000) and (7, 288400), it means that;
Slope = (288400 - 294000)/(7 - 0)
Slope = -5600/7
Slope = -800
Now, we know that the general formula for equation in slope intercept form is; y = mx + c
where; m is slope and c is y-intercept.
Thus;
1) Linear equation is; y = -800x + 294000.

For the savings with 5% interest, the interest on "d" dollars will be expressed as;
[tex]\begin{gathered} \text{Interest = 5\% of d} \\ \text{Interest = 0.05d} \end{gathered}[/tex]Get the total savings plus interest in the first account
[tex]\begin{gathered} \text{Balance}=\text{Initial deposit + Interest} \\ \text{Balance=d+0.05d} \\ \text{Balance=1.05d} \end{gathered}[/tex]Hence the $1.05d will be in the first savings account if Gerard's initial deposit were d dollars
For the other account:
Initial deposit = "d" dollars
Interest = $100
Since the interest will be added to the first deposit, hence;
[tex]\text{Balance=(d+100)dollars}[/tex]In Tabulated form:
