Answer:
2x = 80. On dividing both sides by 2, we obtain. x = 40. x + 15 = 40 + 15 = 55. Hence ... Let the three consecutive multiples of 8 be 8x, 8(x + 1), 8(x + 2). Sum of ... Number after interchanging = 10 × 3x + x = 30x + x = 31x.

what is the value of v in the equation -25=-(4v+7)+10
Answer:
-25 = -(4v+7)+10
-25 = -4v-7+10
-25 = -4v+3
4v = 3+25
4v = 28
v = 28 ÷ 4
v = 7
Answer:
Therefore the value of v in the equation is 7

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = 5x - 1
For x = -1,
y = -5 - 1 = -6
For x = 0,
y = - 1
For x = 1,
y = 5 - 1 = 4

Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
Answer:
6:5
Step-by-step explanation:
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
The algae is spherical in nature
Volume of the algae =4/3 pi r³
Volume of the algae = 4/3×pi×2.5³
Volume of the algae = 62.5/3 pi
Surface area = 4pi r²
Surface area = 4pi ×2.5²
Surface area = 25pi
Taking their ratio
surface area : volume ratio
= 25pi:62.5/3 pi
= 25 × 3/62.5
= 1.2
Hence the required ratio is 12/10 which is 6:5

The Estrada family has established for cable internet service since the pandemic. When establishing the service, there was an initial fee as well as a monthly fee on the contract. c(m)=35m+40 represents this scenario. How much has the Estrada family paid for internet service if they began service in March 2020?
Given:
When establishing the internet service, there was an initial fee as well as a monthly fee on the contract.
The given function is:
[tex]c(m)=35m+40[/tex]
To find:
The cost of internet service if they began service in March 2020.

20 people applied for a job. Everyone either has a school certificate or diploma or even both. If 14 have school certificates and 11 diplomas how many have a school certificate only
Given:
Either has a school certificate or diploma or even both = 20 people
Having school certificates = 14
Having diplomas = 11
To find:
The number of people who have a school certificate only.
Solution:
Let A be the set of people who have school certificates and B be the set of people who have diplomas.
According to the given information, we have
[tex]n(A)=14[/tex]
[tex]n(B)=11[/tex]
[tex]n(A\cup B)=20[/tex]
We know that,
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]20=14+11-n(A\cap B)[/tex]
[tex]20=25-n(A\cap B)[/tex]
Subtract both sides by 25.
[tex]20-25=-n(A\cap B)[/tex]
[tex]-5=-n(A\cap B)[/tex]
[tex]5=n(A\cap B)[/tex]
We need to find the number of people who have a school certificate only, i.e. [tex]n(A\cap B')[/tex].
[tex]n(A\cap B')=n(A)-n(A\cap B)[/tex]
[tex]n(A\cap B')=14-5[/tex]
[tex]n(A\cap B')=9[/tex]
Therefore, 9 people have a school certificate only.

Learning how to simplify an expression is the most important step in understanding and mastering algebra. Simplification of expressions is a handy mathematics skill because it allows us to change complex or awkward expressions into simpler and compact forms. But before that, we must know what an algebraic expression is.
An algebraic expression is a mathematical phrase where variables and constants are combined using the operational (+, -, × & ÷) symbols. For example, 10x + 63 and 5x – 3 are examples of algebraic expressions.
In this article, we shall learn a few tricks on how to simplify any algebraic expression.
How to Simplify Expressions?
Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.
The process entails collecting like terms, which implies adding or subtracting terms in an expression.
Let’s remind ourselves of some of the important terms used when simplifying an expression:
A variable is a letter whose value is unknown in an algebraic expression.
The coefficient is a numerical value used together with a variable.
A constant is a term that has a definite value.
Like terms are variables with the same letter and power. Like terms can sometimes contain different coefficients. For example, 6x2and 5x2 are like terms because they have a variable with a similar exponent. Similarly, 7yx and 5xz are unlike terms because each term has different variables.
To simplify any algebraic expression, the following are the basic rules and steps:
Remove any grouping symbol such as brackets and parentheses by multiplying factors.
Use the exponent rule to remove grouping if the terms are containing exponents.
Combine the like terms by addition or subtraction
Combine the constants

To test the durability of cell phone screens, phones are dropped from a height of 1 meter until they break. A random sample of 40 phones was selected from each of two manufacturers. The phones in the samples were dropped until the screens broke. The difference in the mean number of drops was recorded and used to construct the 90 percent confidence interval (0.46,1.82)
to estimate the population difference in means.
Consider the sampling procedure taking place repeatedly. Each time samples are selected, the phones are dropped and the statistics are used to construct a 90 percent confidence interval for the difference in means. Which of the following statements is a correct interpretation of the interval?
Answer:
See below.
Step-by-step explanation:
I see there are no answer choices you've provided, but in order to interpret a confidence interval correctly, you might say something like "We are 90% confident that the true difference in the mean number of drops is contained within the interval".

Las longitudes de dos lados de un octágono regular están representadas por las expresiones 2x + 4 y 3x-8. Encuentra la longitud de un lado del octágono
Answer:
La longitud del lado del octágono es de 28 unidades.
Step-by-step explanation:
Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:
[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)
A continuación, despejamos [tex]x[/tex] en (1):
[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]
[tex]x = 12[/tex]
Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])
[tex]l = 2\cdot x + 4[/tex]
[tex]l = 28[/tex]
La longitud del lado del octágono es de 28 unidades.

Subtract 180-123 to get the complement of the bottom left and the value of the bottom left, 57°
Since all the interior angles in a triangle will add up to 180° add 57 and 80 to get 137 then subtract 137 to get the value of x, 43.

18x - y = - 42
y= (-43x+34)/20
Answer:
X=-2
Step-by-step explanation:
equation a)
-y=42+18x
equation b)
y= (-43x+34)/20
Solution
42+18x= (-43x+34)/20
20(42+18x)=-43x+34
840+360x = -43x+34
360x+43x=34-840
403x= -806
x= -(806/403)
x= -(2)
x= -2

Find the perimeter of a rectangle with length (x-5) and width (3x+1).
Answer:
8x-8
Step-by-step explanation:
P=s+s+s+s or in this case P= 2l+2w
P= 2(x-5)+2(3x+1)
P=(2x-10)+(6x+2)
P=8x-8
8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1).
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given that,
Length of rectangle = x - 5
Width of rectangle = 3x + 1
Now,
Perimeter of rectangle = 2(width + length)
Perimeter of rectangle = 2(3x + 1 + x - 5)
The perimeter of the rectangle = 8x - 8
Hence "8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1)".

Prove algebraically that the square of any number is always 1 more than a multiple of 8
Answer:
This is interesting but I don't think it's provable (unless it's just the square of odd numbers).
3² = 9, which is 1 more than a multiple of 8 (8)
4² = 16, which is not 1 more than a multiple of 8 (8)
5² = 25, which is 1 more than a multiple of 8 (24)
6² = 36, which is not 1 more than a multiple of 8 (32)
7² = 49, which is 1 more than a multiple of 8 (48)
8² = 64, which is not 1 more than a multiple of 8 (64)
9² = 81, which is 1 more than a multiple of 8 (80)
10² = 100, which is not 1 more than a multiple of 8 (96)
