Answer:
AB = 8
Step-by-step explanation:
Given B is the midpoint of AC , then
AB = AC , that is
7x - 6 = 12 - 2x ( add 2x to both sides )
9x - 6 = 12 ( add 6 to both sides )
9x = 18 ( divide both sides by 9 )
x = 2
Then
AB = 7x - 6 = 7(2) - 6 = 14 - 6 = 8
The sum of three consecutive integers is 147. Find the integers.
The integers are
(Use a comma to separate answers.)
(Answer quickly)
First, let's declare our variables.
x = variable 1
x + 1 = variable 2
x + 2 = variable 3
Now, let's create our expression.
x + x+1 + x+2 = 147
Let's add like terms
3x + 3 = 147
Subtract 3 from both sides
3x = 144
Divide both sides by 3
x = 48
x + 1 = 48 + 1 = 49
x + 2 = 48 + 2 = 50

Subtract -1 3/5 - ( -2 7/8) Enter your answer as a simplified fraction by filling in the boxes
The simplified fraction of the subtraction -1 3/5 - (-2 7/8) is 51/40.
To subtract -1 3/5 from -2 7/8, we first need to find a common denominator for the fractions.
The common denominator for 5 and 8 is 40.
Converting the mixed numbers to improper fractions:
-1 3/5 = -8/5
-2 7/8 = -23/8
Now,
-8/5 - (-23/8)
To simplify,
-8/5 + 23/8
Now, we can rewrite the fractions with the common denominator:
(-8/5) × (8/8) + (23/8) × (5/5)
Simplifying:
-64/40 + 115/40 = 51/40
Therefore, the simplified fraction of -1 3/5 - (-2 7/8) is 51/40.

Step-by-step explanation:
Why can’t one of the names be PNM, or MPN for the plane? But MNP can? What’s the difference, and why?
The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.
For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.

Answer:
The principal was right. The numbers don't add up.
Step-by-step explanation:
Based on the categorization, the total number of students polled is ...
290 +300 +270 -80 -70 -60 -2(50) = 550
The number reportedly polled is 500, so the numbers given are inconsistent.
____
Here's how we understand the categorization.
N(laptop) = N(all three) +N(laptop & tablet) +N(laptop & desktop) +N(laptop only)
N(tablet) = N(all three) +N(laptop & tablet) +N(desktop & tablet) +N(tablet only)
N(desktop) = N(all three) +N(laptop & desktop) +N(desktop & tablet) +N(desktop only)
Then the sum N(laptop) +N(tablet) +N(desktop) is ...
N(L) +N(T) +N(D) = 3N(ltd) +2N(lt) +2N(ld) +2N(td) +N(l) +N(t) +N(d)
where N(L) = number owning a laptop, and N(l) = number owning a laptop only.

The diagonal braces in a fire tower are 20ft long and span a horizontal distance of 12ft. How high does each brace reach vertically?
Answer:
The vertical span or the height which the brace will reach vertically is 16 ft.
Step-by-step explanation:
The diagonal braces in a fire tower will form a right triangle with the horizontal span and height which it will reach vertically.
It is given that,
the length of the brace is [tex]l=20\rm{ft}[/tex]
the horizontal span of the brace is [tex]b=12\rm{ft}[/tex]
Let the height which the brace will reach is [tex]h[/tex].
Now, the brace length will be the hypotenuse of the right triangle and horizontal and vertical span (height) will be the other two sides of the triangle.
So, by using Pythagoras theorem, the vertical span h of the braces will be,
[tex]h^{2}+b^{2}=l^{2}\\h^{2}+12^{2}=20^{2}\\h^{2}=256\\h=16\rm{ft}[/tex]
Therefore, the vertical span or the height which the brace will reach vertically is 16 ft.

Which of the following is an arithmetic sequence?
Answer:
please mark me brainliest pleaseThe figure shows the depths of a submarine.
Find the vertical difference traveled by the submarine
Find the mean hourly vertical distance traveled by the submarine
Answers:
Vertical distance traveled = 410.7 feet
Mean hourly vertical distance = 136.9 feet per hour
=============================================================
Explanation:
We'll subtract the positive versions of the two numbers (large - small) to get
725.6 - 314.9 = 410.7
This tells us that the distance between those depth markers is 410.7 feet
In other words, the submarine has risen 410.7 feet in vertical distance over those 3 hours.
The mean hourly distance, aka the speed, is
speed = distance/time
speed = (410.7 feet)/(3 hours)
speed = (410.7/3) feet per hour
speed = 136.9 feet per hour
This is another way of saying "each hour, the submarine goes up by exactly 136.9 feet".
