A number that is no fewer than 13

Mathematics
2 answers:
Tomtit [17]3 years ago

Answer:12 and down

Step-by-step explanation:

a number is no less than 13, it could equal 13. Next, A > 13. If a number is no less than 13, it could also be greater than 13. Now, put the two together: A ≥ 13, which says A is greater than or equal to 13

Find three consecutive odd integers such that the sum of the smaller two is three times the largest increased by seven
svlad2 [7]
Let the three odd integers be x - 2, x and x + 2
x - 2 + x = 3(x + 2) + 7
2x - 2 = 3x + 6 + 7
2x - 2 = 3x + 13
3x - 2x = -2 - 13
x = -15

The three consecutive odd integers are -17, -15 and -13.

What is the LCD of 2/7 and 9/10
Ksenya-84 [330]
Assuming LCD means Lowest Common Denominator
Assuming by "and" you mean adding the two

Well, you go by the multiples of 7;
7, 14, 21, 28, 35, 42, 49, 56, 63,<u> 70</u>
Multiples of 10;
10, 20, 30, 40, 50, 60, <u>70</u>, 80, 90, 100

Straight away you can see the lowest common multiple is 70,

Now to go about adding them,
2/7 * 10 (both sides) , 20/70
9/10 * 7 (both sides) , 63/70

Then you add the two; 20/70 + 63/70  - now we can add them because they share the same denominator
20/70 + 63/70 = 83/70 = 1 whole 13/70 (simplified)

<u>The LCD is 70

Quick tip, </u>to find a common multiple (not necessarily the lowest) multiply the two denominators.

Solving for y. - y = -2x -5
Effectus [21]

Answer:

y = 2x+5

Step-by-step explanation:

Add y on both sides, this cancels out the y on the left side

add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.

<u>OR </u>

Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.

If you needed a value for y, more info is needed.

hope this helps (:

Question 1
Vitek1552 [10]

Answer:

M.A.D= 4.9

Step-by-step explanation:

Given

12.7, 22, 23.5, 24, 11, 22

Required

Determine the M.A.D

Start by calculating the Mean

Mean = \frac{\sum x}{n}

In this case, n = 6

So:

Mean = \frac{12.7 + 22 + 23.5 + 24 + 11 + 22}{6}

Mean = \frac{115.2}{6}

Mean = 19.2

Subtract the mean from each element

12.7 - 19.2 = -6.5

22 - 19.2 = 2.8

23.5 - 19.2 = 4.3

24 - 19.2 = 4.8

11 - 19.2 = -8.2

22 - 19.2 = 2.8

Take absolute value of the results above

|-6.5| = 6.5

|2.8| = 2.8

|4.3| = 4.3

|4.8| = 4.8

|-8.2| = 8.2

|2.8| = 2.8

The mean of the above gives the MAD

M.A.D= \frac{\sum |x - u|}{n}

M.A.D= \frac{6.5 + 2.8 + 4.3 + 4.8 + 8.2 + 2.8}{6}

M.A.D= \frac{29.4}{6}

M.A.D= 4.9
