A number is divided by 7. Thirty-five is added to the quotient. The result is 65. What was the original number?
Answers
Answer:
210
Step-by-step explanation:
Firstly I decided to call the original number 'x'
I then ran through the processes the question stated: x/7 + 35 = 65
The quotient means the result obtained by dividing two numbers so in this case that would be the result of dividing the number by 7
Now I solved 'x' (the original number) using the equation i created
x/7 + 35 = 65
The goal is to get 'x' on one side by itself so i started by taking away 35 from both sides: x/7 + 35 - 35 = 65 - 35
So i ended up with x/7 = 30
Then to get rid of the fraction (i.e. get 7 out of that side of the equation) i multiplied both sides by 7: x/7 multiplied by 7 = 30 multiplied by 7
So i ended up with the answer x = 210

How many whole numbers are less than k,If k is a whole number
Answers
If k = 3, then the whole numbers less than 3 are 2, 1, and 0. There are 3 whole numbers less than 3.
If k = 10, then the whole numbers less that 10 are 9, 8, 7, 6, 5, 4, 3, 2, 1, and 0. That's 10 whole numbers less than 10.
It appears that there are k whole numbers less than the whole number k.

Find the distance between the pair of points. (6,16) and (-22,12)
Answers
Answer:
28.3 units (3 s.f.)
Step-by-step explanation:
[tex]\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }[/tex]
Using the formula above,
distance
[tex] = \sqrt{[6 - ( - 22)]^{2} + (16 - 12) {}^{2} } [/tex]
[tex] = \sqrt{(6 + 22) {}^{2} + {4}^{2} } [/tex]
[tex] = \sqrt{ {28}^{2} + 16 } [/tex]

hope this helps! :)
HJ and JH is the two representation of the given line segment.
What is a line segment?
A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
A line segment can be represented in two ways one is either one end to another and the second is opposite to the other.
The denotation of a line segment let's say AB is representing the length of the line segment.
And length can never change by measuring either one end or another.
So HJ and JH are two ways to represent the line segment.
Hence "HJ and JH is the two representation of the given line segment".

Parallel to x + y = 4 and passes through M(3, 2)
Answers
Answer:
x + y = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x + y = 4 ( subtract x from both sides )
y = - x + 4 ← in slope- intercept form
with slope m = - 1
Parallel lines have equal slopes , then
y = - x + c ← is the partial equation
To find c substitute (3, 2 ) into the partial equation
2 = - 3 + c ⇒ c = 2 + 3 = 5
y = - x + 5 ( add x to both sides )
x + y = 5 ← equation of parallel line

Approximately 490 000 cases of coronavirus have been confirmed in Guatemala. If in the United States are 40 000 000 cases confirmed. By how many times, do coronavirus cases from the U.S surpass Guatemala’s?
Answers
Using proportions, it is found that:
A regular chicken has a weight of 57.4 grams.Coronavirus cases from US surpasses Guatemala by 81.63 times.
------------------------
These questions are solved by proportions, using rules of three.
------------------------
One feather has 0.0082 grams.How many grams are there in 7000 feathers?
1 feather - 0.0082 grams
7000 feathers - x grams
Applying cross multiplication:
[tex]x = 0.0082 \times 7000 = 57.4[/tex]
A regular chicken has a weight of 57.4 grams.
------------------------
Considering the number of cases in Guatemala equivalent to 1, we find the ratio for the number of cases in the US.
490 000 - 1
40 000 000 - x
Applying cross multiplication:
[tex]490000x = 40000000[/tex]
[tex]x = \frac{40000000}{490000}[/tex]
[tex]x = 81.63[/tex]
Coronavirus cases from US surpasses Guatemala by 81.63 times.
