Answer:
x=1
Step-by-step explanation:
(x+1)(x+2)(x+3)(x+4)=120
Split 120 in it's factors: 2x3x4x5
=>(x+1)(x+2)(x+3)(x+4)=2x3x4x5
=>x+1=2 (Take any one in order)
=>x=1
Answer:
x=1
Step-by-step explanation:
120=2^3*3*5=2*3*4*5=(x+1)(x+2)(x+3)(x+4)
so x+1=2
-1 -1
x=1

If km = 67 what is LM
Answer:
LM = 28 units
Step-by-step explanation:
Length of segment KL = (4x + 7) units
Length of segment LM = (5x - 12) units
Length of LM = 67 units
Since length of KM = length of KL + length of LM
By substituting the given values in the expression,
67 = (4x + 7) + (5x - 12)
67 = (4x + 5x) + (7 - 12)
67 = 9x - 5
9x = 67 + 5
x = [tex]\frac{72}{9}[/tex]
x = 8
Therefore,
LM = (5x - 12)
= (5×8) - 12
= 40 - 12
= 28
Length of segment KM is 28 units.

how would you solve for 5x=13 for x
Answer:
divide by 5: x = 13/5 = 2.6
Step-by-step explanation:
Make use of the properties of the multiplicative inverse and the multiplication identity element. Multiplying both sides of the equation by the multiplicative inverse of the coefficient of x makes the result be 1x on the left side.
(1/5)(5x) = (1/5)(13)
1x = 13/5
The multiplicative identity element (1) does not change the value of what it multiplies, so this simplifies to ...
x = 13/5
_____
Effectively, we divide (both sides) by 5.
The answer is 37. Use addition multiplication and must have a fraction showing the equation
that is correct because 37/ one and 37×1
this is the correct answer
Does meditation cure insomnia? Researchers randomly divided 400 people into two equal- sized groups. One group meditated daily for 30 minutes, the other group attended a 2-hour information session on insomnia. At the beginning of the study, the average difference between the number of minutes slept between the two groups was about 0. After the study, the average difference was about 32 minutes, and the meditation group had a higher average number of minutes slept. To test whether an average difference of 32 minutes could be attributed to chance, a statistics student decided to conduct a randomization test. She wrote the number of minutes slept by each subject in the study on an index card. She shuffled the cards together very well, and then dealt them into two equal-sized groups. Which of the following best describes the outcome?
Answer:
this is very long be shot question
Step-by-step explanation:
The best outcome will be that the average difference between the two sacks will be about Zero minutes.
Randomization TestAs per the question, at the beginning of the study the average difference was seen as 0 minutes, but after the experiment the average difference was of 32 minutes.
To Cross examine the study result, the researcher recorded the number of minutes slept on an index card and shuffled the cards into two equal parts. There can be three outcomes of this test, these are:
The average difference will be about 0 minutes. The average difference will be more than 32 minutes.The average difference will be about 32 minutes.There is three outcomes because of shuffling of the cards.

What is another way to name line l?
Answer:
Line UM.
Step-by-step explanation: you can name a line by naming at least two points on it.
Line l can be called line UM, line LM, and line UL because line l is contained in plane S.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
m is the ratio of the line,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases.
It is given that:
A plane S contains a line l.
It is possible to give a name for line l in different ways.
The line l can be called:
Line UMLine LMLine ULLines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.
Thus, line l can be called line UM, line LM, and line UL because line l is contained in plane S.

A book has 89 pages, but the page numbers are printed incorrectly. Every third page number has been omitted, so that the pages are numbered 1,2,4,5,7,8,... and so on. What is the number on the last printed page?
Answer:
89
Step-by-step explanation:
There are only 30 pages but last page number is 89.
The last page of the book would be with the number 89. For details, check the calculations below.
Number SystemThe number system is characterized as the arrangement or sequence in which the numbers are arranged in a mathematical order beginning from 0 in whole numbers.
In the given situation,
We know that,
Total pages available in the book = 30
And every third page is omitted from the book due to misprinting of the page numbers.
If we divided 90/3 = 30 pages are there. Hence, the last page would be 89 itself.
Thus, the above response is correct.

what is 7 1/3 as a improper fraction
Answer:
22/3
Step-by-step explanation:
First, I multiplied 7 and 3 because 7 is the whole number and 3 is the denominator of the fraction.
7*3=21
Then, I added 21 to 1 because 1 is the numerator in the fraction.
21+1=22
Finally, I made it 22/3 because the denominator of the fraction is 3.
So, your final answer is 22/3.

If 4700 bricks each of size 25 cm x 16 cm x 10 cm are required to construct a wall
20 m long and 20 cm wide containing two windows of size 2 m X 1.5 m each, find
the height of the wall.
Answer:
970 cm
Step-by-step explanation:
Given that:
Size of brick :
25cm × 16cm × 10cm
Number of bricks = 4700
Dimension of wall = 20 m long × 20 cm wide
Let the height = h
Hence, dimension of wall (length and height)
2000 cm × h
Dimension of window = 2m × 1.5m = 200cm × 150cm
Number of windows = 2
Total area covered by windows = 2 * (L * B)
= 2(200 * 150) = 60,000cm
Brick = (25 * 16) * 4700 = 1, 880, 000 cm ( length and height)
Wall = 2000 * height - 60,000 = 1880000
2000height - 60,000 = 1880000
2000height = 1880000 + 60,000
2000height = 1940000
Height = 1940000 / 2000
Height of wall = 970 cm
