1. Suppose we have two consecutive odd integers. If the smaller one is “x” ; what would we call the large one?
2. We are told there are two consecutive odd integers and the smaller one is 12 more than one third the large one. Use the answer to problem 1 to write a clean equation then find the integers
Main Answer:1) (x + 2)
2) The numbers are 19 and 21.
Concept and definitions should be there:
An odd integer n is an integer which is not a multiple of 2 (or equivalently one more than a multiple of 2). The odd integers are ..., -5, -3, -1, 1, 3, 5, ... Every odd integer can be written in the form 2k + 1 for some unique integer k.
The product of any two odd integers is odd and the result of a division where both the dividend and the divisor are odd is odd. But the sum and difference of any two odd integers are even.
The sum and difference of an even integer and odd integer are odd. Besides 2, all prime numbers are odd. Also, odd integers are really cool
This article is a stub. Help us out by expanding it.
Given data:
1) We have two consecutive odd integers.
Solving part:
Remember that the distance between any two consecutive odd numbers is 2.
5 - 3 = 2
7 - 5 = 2
13 - 11 = 2
etc.
So if the smaller of the two odd numbers is x, then the larger one will be (x + 2).
Given that:
2) We have two consecutive odd numbers, let's write them as:
Solving part:
(2*n + 1) and (2*n + 3)
Where n is an integer number.
We know that the smaller one is 12 more than one third of the larger one, so we have:
(2*n + 1) = 12 + (2*n + 3)/3
Now we can solve this for n
2*n + 1 = 12 + (2/3)*n + 1
2*n - (2/3)*n = 12 + 1 - 1
(4/3)*n = 12
n = (3/4)*12 = 9
n = 9
Then the two consecutive odd integers are:
(2*n + 1) = (2*9 + 1) = 19
(2*n + 3) = (2*9 + 3) = 21
Final Answer:1) (x + 2)
2) The numbers are 19 and 21.

Find an equation for the line which passes through (-2,8) and is perpendicular to the line containing (0,1) and (4,5).
The equation of line which passes through (-2, 8) and perpendicular to the line conatining (0, 1) and (4, 5) is y = -x + 6 .
Let the equation of line passes through the point (-2, 8) be y = mx + b.
Where m is the slope of the line and b is the y intercept of the line.
According to the given question.
A line passes through the points (-2, 8).
And it is also perpendicular to the line containing (0, 1) and (4, 5).
Since, the line is perpendicualr to the line conatining (0, 1) and (4, 5).
So, the slope of the line whose equation is to be find is given by
m = -1/(5 - 1/4-0)
⇒ m = -1/4/4 = -1
Thereofre, the equation of line with slope -1 is
y = -1x + b
Also, it passes through (-2, 8)
So,
8 = -1(-2) + b
⇒ 8 - 2 = b
⇒ b = 6
Thereofore, the equation of line which passes through (-2, 8) and perpendicular to the line conatining (0, 1) and (4, 5) is y = -x + 6 .

balance:
$2,500 for 25 years at
2.75% annual simple
interest
Show work
Answer:
$4,218.75
Step-by-step explanation:
The formula for computing simple interest I on a principal amount P for t years at an interest rate of R% is given by
I = Prt
The ending balance amount is found by adding the principal to the interest computed
Ending balance = P + I
Here r is the interest rate in % converted to a decimal. This is done by dividing by 100
r = R/100 = 2.75%/100 = 0.0275 per year
I = 2500 x 0.0275 x 25 = 1718.75
So interest I = $1718.75
Ending balance = $2,500 + $1718.75 = $4,218.75
China generated 237.188 billion kilowatt-hours (kWh) of wind energy in 2018. The population in China in 2018 was 1.379 billion. What was the wind energy generated per capita? Give your answer to the nearest hundredth.
Answer:
172 kilowatts.
Step-by-step explanation:
Energy : 237.188 billion = 237,188,000,000 = 2.37188 × 10¹¹
People : 1.379 billion = 1,379,000,000 = 1.379 × 10⁹
Divide both values : 2.37188 ÷ 1.379 = 1.72; 10¹¹ ÷ 10⁹ = 10² ⇒ 1.72 × 10² or 172 kilowatts.

Which table represents y as a function of x?
[tex]{ \qquad\qquad\huge\underline{{\sf Answer}}} [/tex]
An equation represents a represents only when there is a unique value of x for every value of y. when it represents u as a function of x.
i.e if we draw lines parallel to y axis and it cuts the curve two or more than two times at a particular value of x then it doesn't represent a function at all.
And as we can see in the given tables,
1.) 12.23 is the value of x for both 5.4 and 6.4
2.) 0.31 is the value of x for both 55 and 59
4.) 20 is the value of x for both 245 and 255

Which fraction is greater, 35/109 or 36/104?? To explain your answer, use our definition of fraction along with reasoning other than finding common denominators, common numerators, cross-multiplying, or converting to decimals.
The fraction that is greater is 36/104 since 34.62% is greater than 32.11%
Percentages and ratioFractions are written as the ratio of two integers. For instance a/b is a fraction.
In order to determine which of the fractions is greater, we will express them as percentage as shown:
35/109 * 100
3500/109
32.11%
Similarly;
36/104 * 100
3600/104
34.62%

based on the equation 5×x+860=2×x+380, you can say
The value of x is -160.
An equation in which the power of any variable is not more than one is called a linear equation.
Here, we are given a linear equation as follows-
5 × x + 860 = 2 × x + 380
⇒ 5x + 860 = 2x + 380
Let us solve the given equation-
Subtracting 2x from both sides, we get
5x - 2x + 860 = 2x - 2x + 380
3x + 860 = 380
Subtracting 860 from both sides-
3x + 860 - 860 = 380 - 860
3x = -480
dividing both sides by 3,
3x/3 = -480/3
x = -160
Thus, the value of x comes out to be -160.

Random means by chance.

Answer:
True
Step-by-step explanation:
Because you never expect when something may show up once your doing something and forget about what you lost a while back. Sometimes it just pops up and we're like, "Oh that's where it was".
Can't say true or false because both can be answers in different cases, mathematically speaking you can select one thing from a set of similar things having similar chance to be selected. and again you can also select one thing at random from a set of things having different chance of being selected. in my perspective:)
and maybe the question has more chance to be false because if a statement is false at least in one case it is false.

what is the value of x?
help would be so appreciated
Answer:
x = 23
Step-by-step explanation:
The two angles are supplementary angles.
Supplementary angles sum 180°
(6x+4) + 38 = 180
6x + 42 = 180
6x = 180 - 42
6x = 138
x = 138/6
x = 23
Check:
6*23 + 4 + 38 = 180
138 + 42 = 180
Answer:
x = 23Step-by-step explanation:
We know that the sum of angles of a linear pair is always equal to 180°. These angles are also known as supplementary angles.
[tex]\bf 6x+4+38^o=180^o[/tex] (Add numbers)
[tex]\bf 6x+42=180[/tex] (Simplify)
[tex]\bf 6x+42-42=180-42[/tex](Subtract both sides by 42)
[tex]\bf 6x=138[/tex] (Simplify)
[tex]\bf \cfrac{6x}{6}=\cfrac{138}{6}[/tex] (Divide both sides by 6)
[tex]\bf x=23[/tex]
Therefore, x = 23.

Hall dimensions 200m by 85m. Diagram office wall scale 1:40. What are the dimensions of floor space in cm
The dimensions of floor is 500 cm by 212.5 cm
HOW TO FIND DIMENSION OF HALL ?Multiply the width and length of each rectangle to find its area. The areas of each rectangle are then added up to determine the total area. In the event that your room is L-shaped, for instance, this can be split into two rectangles. Additionally, this method still works in a complicated room.
CALCULATION500 cm by 212.5 cm
Given :
The main arena hall has dimensions 200 m by 85 m.
On a large diagram on the office wall the scale is 1:40.
Length of arena hall = 200 m
Scale is 1:40
So, the length of the floor =
Since 1 m = 100 cm
So, 5 m = 100*5 = 500 cm
Width of arena hall = 85 m
So, width of floor =[tex]\frac{85 * 1}{40}[/tex] = 2.125m
Now 1 m = 100 cm
So, 2.125 m = 212.5 cm
Thus the dimensions of floor is 500 cm by 212.5 cm
