Answer:

see below

Step-by-step explanation:

Since AB + BC = AC, x + 3x = 20 → 4x = 20 → x = 5.

AB = x = 5 and BC = 3x = 3 * 5 = 15.

If a point has a negative x-coordinate, and its y-coordinate is positive, where does the point lie relative to the origin? Expla

Daniel [21]

If a coordinate has a negative x-coordinate and its y-coordinate is positive, then the point is on the 2nd quadrant.
That means that the point is left of the origin and above it.

Find the slope of the line that contains the<br><br>point (4, −9) and has a y intercept of 2.

ASHA 777 [7]

Answer:

Step-by-step explanation:

The equation of a line with slope of <em>m</em> and y-intercept of <em>b</em> is: y = mx + b

b = 2 and line contains the point (4, -9), so:

-9 = m×4 + 2 {subtract 2 from both sides}

-11 = 4m {divide booth sides by 4

m = -¹¹/₄

why is using the metric system superior to using the standard system of measurement... Please someone help I need this and I tri

PilotLPTM [1.2K]

Metric is used world-wide and is used everywhere except in english places (britan and USA)

some examples why metric is nice

base 10 system
1cm=10mm=0.1m=0.01km
1cm^3=1ml
1000cm^3=1L
1000ml=1L

0 C⁰=freezing tempurature
100 C⁰=boinling tempurature

in english
12in=1foot
3ft=1yd
16oz=1lb
8oz=1cup
3tsbs=1tbs
2c=1pt
2pt=1qt
4qt=1gal
32 F⁰=freezing
2hundred something=boiling

metric is nice because everything is in multiplules of 10

and also this exerpt from a book
"<span>In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade which is 1 per cent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system the answer to <em>'How much energy does it take to boil a room-temperature gallon of water?'</em> is go **** yourself because you can't directly relate any of those quantities "</span>

A website had 826, 140 hits last month what is the value of the 8 in 826,140

Angelina_Jolie [31]

800,000 or eight hundred thousand.

<h3>Further explanation</h3>

<u>Problem:</u> The given number is 826,140.

<u>Question:</u> What is the value of the digit 8?

<u>The Process:</u>

This is a problem with place value.

Let us set the place values from 826,140 consecutively as follows.

In the thousands period: 8 hundred thousands, 2 ten thousands, 6 one thousands.
In the units period: 1 hundreds 4 tens 0 ones.

Let us say in word form: eight hundred twenty-six thousand six hundred forty.

Hence, the value of the 8 in the numbers 826,140 is 800,000 or eight hundred thousand.

<u>Extra:</u>

What is the value of the digit 6 in the numbers 826,140? The answer is 6,000 or six thousand.

- - - - - - -

<u>Notes:</u>

Recall that the digits in large numbers are in groups of three places, i.e.,

hundreds,
tens, and
ones (or units).

The groups are called periods, i.e.,

millions period
thousands period
ones or units period

Commas are typically used to separate the periods.
