The smallest possible value of the sum of the eight integers is given by:
116.
What are the integers?The eight integers in the problem are given as follows:
n, ..., n + 7.
Hence:
The smallest integer is of n.The largest integer is of n + 7.The smallest integer is more than 3/5 of the largest integer, hence the following inequality is built to relate them:
n > 3/5(n + 7)
Applying the distributive property on the right side, we have that:
n > 0.6n + 4.2.
0.4n > 4.2
n > 4.2/0.4
n > 10.5.
Hence the integers are:
11, 12, 13, 14, 15, 16, 17, 18.
(as 11 is the smallest integer possible).
Then the value of the sum is obtained as follows:
11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 116.

What is the equation of this line in standard form?
A - 9x−8y=23
B - 8x−9y=−23
C - 8x−9y=23
D
8x−7y=−25
Answer:
The correct answer is B
Step-by-step explanation:
I went a weird way to get this. I wrot the line in the slope intercept form and then converted it to the standare form.
For the slope intercept form I need a slope and a y interctp. I used the two points given to find the slope. The slope is the change in y over the change in x. From the points the y values are 3 and -1. The x values are 1.2 and -4
[tex]\frac{3 - -1}{\frac{1}{2}- - 4 }[/tex] = [tex]\frac{3+1}{\frac{1}{4}+4 }[/tex] = [tex]\frac{4}{\frac{9}{2} }[/tex]
4 ÷[tex]\frac{9}{2}[/tex] = [tex]\frac{4}{1}[/tex] x [tex]\frac{2}{9}[/tex] = [tex]\frac{8}{9}[/tex]
[tex]\frac{8}{9}[/tex] is the slope
Now to find the y intercept
I will use
slope [tex]\frac{8}{9}[/tex] (m)
y = -1 from the point (-4,-1) given
x = -4 from the point (-4,-1) given
y=mx + b
-1 = [tex]\frac{8}{9}[/tex](-4) + b
-1 = [tex]\frac{-32}{9}[/tex]x + b Add [tex]\frac{32}{9}[/tex] to both sides
[tex]\frac{23}{9}[/tex] = b
y = [tex]\frac{8}{9}[/tex]x + [tex]\frac{23}{9}[/tex] Multiply all the way thorugh by 9
9y = 8x + 23 Subtract 9y from both sides
0 = 8x -9y + 23 Subtract 23 from both sides
-23 = 8x -9y
or
8x -9y = -23

A base-10 three digit number $n$ is selected at random. Which of the following is closest to the probability that the base-9 representation and the base-11 representation of $n$ are both three-digit numerals?
A. 0.3 B. 0.4 C. 0.5 D. 0.6 E. 0.7
The probability that the representation in base-9 and the representation in base-11 are both three-digit numbers is 0.6753 which is approximately 0.7 option E.
Given,
We require the following inputs to determine the probability that both the base-9 representation and the base-11 representation are three-digit numbers:
The lowest base 10-based 3-digit base-11 numberThe largest three-digit base 9 in base 10 number.The total amount of 3-digit base-10 numbersThe base-11's lowest 3-digit number is 100.
The comparable number is 121 when expressed in base 10.
888 is the biggest 3-digit base-9 number.
The corresponding number is 728 when expressed in base 10.
As a result, there are the following possibilities:
Possibilities = 728 - 121 + 1
Possibilities = 608
The total number of 3-digit base-10 numbers is
Count = 999 - 100 + 1
Count = 900
The necessary probability is:
P = 608/900
Evaluate
P = 0.6753 ≈ 0.7

your solutions.
2x + 3y = 7
-2x + 4y = 14
Answer:
(- 1, 3 )
Step-by-step explanation:
2x + 3y = 7 → (1)
- 2x + 4y = 14 → (2)
add (1) and (2) term by term to eliminate x
(2x - 2x) + (3y + 4y) = (7 + 14)
0 + 7y = 21
7y = 21 ( divide both sides by 7 )
y = 3
substitute y = 3 into either of the 2 equations and solve for x
substituting into (1)
2x + 3(3) = 7
2x + 9 = 7 ( subtract 9 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
As a check
substitute the values of x and y into the left side of both equations and if equal to the right side in both equations then the values of x and y are true.
(1) 2(- 1) + 3(3) = - 2 + 9 = 7 ← true
(2) - 2(- 1) + 4(3) = 2 + 12 = 14 ← true
then (- 1, 3 ) is the solution to the system

A wholesale food supplier charges x dollars for each bag of flour and y dollars for each bag of sugar. Bakery A purchases seven bags of flour and five bags of sugar for a total cost of $260.45. Bakery B purchases five bags of flour and three bags of sugar for a total cost of $171.35. What is the cost of each bag of flour? Each bag of sugar?
The cost of each bag of flour is $ 18.85 and the cost of each bag of $ 25.7 which a wholesale food supplier charges for each bag of flour and for each bag of sugar.
Given that:
The cost of each bag of flour = x dollars
The cost of each bag of sugar = y dollars
Bakery A purchases seven bags of flour and five bags of sugar for a total cost of $260.45.
Bakery B purchases five bags of flour and three bags of sugar for a total cost of $171.35.
Making equation from both the above statements. We get,
7x + 5y = 260.45 ...... (1)
5x + 3 y = 171.35 ....... (2)
Multiplying equation (1) by 5 and equation (2) by 7. We get the value,
35x + 25y = 1302.25 ....... (3)
35x + 21y = 1199.45 ........ (4)
Subtracting equation (4) from (3). We get,
4y = 102.80
=> y = $ 25.70
Putting the value of y in equation (1). We get,
7x + 25.70 x 5 = 260.45
7x = 260.45 - 128.5
7x = 131.95/7
=> x = $ 18.85
Hence, we can say that a wholesale food supplier charges 18.85 dollars for each bag of flour and 25.7 dollars for each bag of sugar.

which graph represents y=-2x
A graph which represents the linear function y = -2x is: graph B.
What is a graph?In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.
Generally speaking, the graph of any proportional relationship is characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) either increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.
In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in the graph of y = -2x is proportional as it passes through the origin (0, 0).

Basic Proportionality Theorem (can be abbreviated as BPT) states that, if a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.
For x

DG + GE = DE
DE = 2(DG)
DG/DE = 1/2
hence GH/EF = 1/2
By Basic Proportionality Theorem ( BPT )
(x – 3) / 28 = 1/2
after cross multiplication
2(x – 3) = 28
2x – 6 = 28
2x = 34
x = 17
For y
By Basic Proportionality Theorem (BPT) to side DF
DF = 2(DH)
DH/DF = 1/2
(y + 8) / (y + 8 + x – 7) = 1/2
after cross multiplication
2(y + 8) = y + 8 + x – 7
put x = 17
2(y + 8) = y + 8 + 17 – 7
2(y + 8) = y + 18
2y + 16 = y + 18
2y = y + 2
2y – y = 2
